If you go read a book, memorize it, write it down later in a substantively similar form, and share it freely or sell it — yes, you might get into copyright trouble. It has happened before and it is at best a tricky gray area.

If you pick up a book and learn a fact, then yeah, you’re allowed to share that fact.

It’s weird that this topic keeps devolving into a form of “so what, it’s illegal for me to learn things?” Because: no, it’s not. And: You and a piece of software are treated differently under the law. You have a different set of rights than ChatGPT.
