No. That is NOT what humans do unless you somehow learn grammar without going to school. Most of a human's childhood is spent learning from their parents so that they can move about and communicate at least a little effectively. Then, they go to school and learn rules, social, grammar, math, and so forth. There's some learning via copyrighted works (such as textbooks, entertainment, etc.), but literally, none of this is strictly required to teach a human.

Generative AI, however, can ONLY learn via the theft of copyrighted works. Whether this theft is covered under fair use is left to be seen.
