We all get our protein from gut bacteria, or at least thanks to gut bacteria. In nutrition, “protein” refers to the collection of the proteins (amino-acid chain macromolecules) that we can digest. The rest of the proteins (the proteins we can not digest) are called “fiber” in nutrition.
Foregut fermenters turn all of protein ingested, in addition to ingested nitrogen like urea, into base blocks like ammonia and then back into bacterial proteins that have much better amino acids. They are creating the amino acids they need, roughly in the quantities needed. In humans this does not happen in any meaningful way - we must eat the amino acids we need.

Well, that is cheating.
