[Verginius Rufus]

When you go back a few generations you have ancestors from whom you have inherited no DNA...yet without them having existed and produced children, you would not exist. The amount you can inherit can vary greatly. I have two matches on "FamilyTreeDNA" who are the exact same relationship to me on paper--we have the same set of great-great-grandparents--but one of them is one of my closest matches and the other one is in the lower half of the matches FTDNA shows (they cut it off when the shared centiMorgans falls below a certain number).

Before doing any DNA tests, I watched some YouTube videos about the tests. One featured someone with well-documented American Indian ancestry but none showed up in the DNA testing. (I don't think that's the case with Elizabeth Warren--I think she was just fabricating the supposed ancestry.)

Precisely. Most people have 46 family trees; thus, at the gggg-grand level, of the 64 possible slots, at least 18 of them passed down nothing to each of us.
