Relevant portion of the 14th amendment:

“All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.”

The understanding of “and subject to the jurisdiction thereof” would seem to be the relevant point.

Relevant portion of the 14th amendment: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.”

I actually think the later portions are equally relevant here:

"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside. No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."

Specifically, there is a distinction made between a "citizen" (narrowest group), "any person" (broadest group), and "person within its jurisdiction" (middle point).

This tells me that the first clause (the portion you cited) where it says "and subject to the jurisdiction thereof" requires more than merely being a "person within its jurisdiction" (that is, here in the USA for any reason, like being born here to illegals). Note that "within in jurisdiction" has been held to mean "here inside the USA or a State". Which means the drafters intended that "subject to the jurisdiction" mean something more narrow than merely being "within" the State or USA.

Long way of saying, you are 100% correct, and the rest of Section 1 confirms what you believe.

Illegals do not “reside” anywhere, in my mind.
Is squatter residing in the house he invited himself into against the will of the owners?

There are many cases where pregnant woman just makes it across the border to get birth.
Is she residing in US for few hours?
