If you ask ChatGPT the rules for D&D, the private sourcebooks are all in there.

Whoever told you that is lying to you. You are not legally allowed to personally memorize and recite copyrighted works all you want, any more than you're allowed to personally memorize, write down copyrighted works, and distribute them as much as you want.
All piracy is a process of computer-assisted remembering and reciting.
I can't go write and commercialize what I learnt directly, but I'm not breaking the law by quickly seeing how some book I didn't buy ends so I can talk about it at a party - and then everyone knows how it ends which might affect whether they want to buy said book and upset the author. But, tough shit, what I did was legal. I can even use the ending as one set of input from dozens of inspirations for my own book where the end result is transformative enough where the sources are unrecognizable. And if I had learnt about the endings from a dozen books without buying those books I didn't break any laws even though I am now commercializing something in being inspired by them all to make something new.
Being non-commercial is not an automatic fair use exception. Being commercial does not preclude fair use. And rule concepts are not copyrightable, only the specific expression. Rules may have other IP protection, including patents.
That's not even true in the US anymore. You'd have to convert those rules into some sort of device, or argue that the game is a business method.
The rules of games cannot be copyrighted either. The artistic elements can be trademarked, but if ChatGpt merely explains the rules to you in different ways, that isn't infringement either.
...wait, isn't that false? legitimately asking.
or is it because it was done by a corporation that makes it illegal?
im thinking of how restaurants dont sing happy birthday and fair use restrictions etc
If I recite them to myself, in my home, it's fine. If I do it at a gathering at my house where we're playing D&D, fine. If I do it as a performance, in front of a crowd, or as a recording, now I'm no longer fine. Context matters in a copyright cases. Not to mention, to claim fair use, you do have to claim you violated copyright. Fair use is just an allowed violation.
As to Happy Birthday, that's actually ok for them to do now. The person/group that held the copyright to Happy Birthday was found to have not actually have held them in the first place. Happy Birthday is actually an older song called "Good Morning to All". Swap "Good Morning" with "Happy Birthday" and "children" with "dear [PERSON]" and you have the lyrics. This was not deemed a substantive change. And since the copyright on "Good Morning to All" has lapsed, Happy Birthday is in the public domain.
I can give you a rock that I own, which I hope we all agree is not copyrightable, and ask you to sign a license that you will keep it indoors. If you put it in your yard, you are breaking the license and potentially liable. This has nothing to do with copyright.
