This is the 12th Amendment and it says no such thing.
Amendment XXII (1951)
Section 1.
No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once. But this article shall not apply to any person holding the office of President when this article was proposed by the Congress, and shall not prevent any person who may be holding the office of President, or acting as President, during the term within which this article becomes operative from holding the office of President or acting as President during the remainder of such term.
Umm...That's the Twenty-Second Amendment. XXII is twenty-two in Roman Numeral. Twelve is XII in Roman Numerals.
Here's the Twelfth Amendment:
[Article XII] (Amendment 12 - Election of President)
The Electors shall meet in their respective states, and vote by ballot for President and Vice-President, one of whom, at least, shall not be an inhabitant of the same state with themselves; they shall name in their ballots the person voted for as President, and in distinct ballots the person voted for as Vice-President, and they shall make distinct lists of all persons voted for as President, and of all persons voted for as Vice-President, and of the number of votes for each, which lists they shall sign and certify, and transmit sealed to the seat of the government of the United States, directed to the President of the Senate;—The President of the Senate shall, in the presence of the Senate and House of Representatives, open all the certificates and the votes shall then be counted;—The person having the greatest number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice. And if the House of Representatives shall not choose a President whenever the right of choice shall devolve upon them, before the fourth day of March next following, then the Vice-President shall act as President, as in the case of the death or other constitutional disability of the President.14 —The person having the greatest number of votes as Vice-President, shall be the Vice-President, if such number be a majority of the whole number of Electors appointed, and if no person have a majority, then from the two highest numbers on the list, the Senate shall choose the Vice-President; a quorum for the purpose shall consist of two-thirds of the whole number of Senators, and a majority of the whole number shall be necessary to a choice. But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States.
Emphasis added, a wall of text because that's the way it's written.

Clause 2: Method of choosing electors
Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector.
Under the U.S. Constitution the president and vice president are chosen by electors, under a constitutional grant of authority delegated to the legislatures of the several states. The Constitution reserves the choice of the precise manner for creating electors to the will of the state legislatures. It does not define or delimit what process a state legislature may use to create its state college of electors. In practice, the state legislatures have generally chosen to create electors through an indirect popular vote, since the 1820s. Most states have a “winner-take-all” system in which the candidate with the most votes in the state gets all the electoral votes.[6] Maine and Nebraska allow individual congressional districts to elect one elector.
In an indirect popular vote, it is the names of the candidates who are on the ballot to be elected. Most states do not put the names of the electors on the ballot.[6] It is generally understood by the voters and the electors themselves that they are the representative “stand-ins” for the candidates and are expected to cast their electoral college ballots for the president and vice president who appeared on the ballot. The actual electors being voted for are usually selected by the candidate’s party. There are a few cases where some electors have refused to vote for the designated candidate. (See “Faithless Elector”.) Many states have mandated in law that electors shall cast their electoral college ballot for the designated presidential candidate.[6] The constitutionality of such mandates was established on July 6, 2020 by the SCOTUS.
Each state chooses as many electors as it has representatives and senators representing it in Congress. Under the 23rd Amendment, the District of Columbia may choose no more electors than the state with the lowest number of electoral votes (in effect, three electors), although since that amendment’s ratification the District’s population has never reached the threshold that would otherwise entitle it to choose four or more electors. U.S. senators, representatives and federal government officials are barred from becoming electors; in practice, the two major federal parties frequently select senior state party and government officials (up to and including governors) to serve as electors.
