Gambling is probably one of the things you'd rarely see any changes from lol. I don't think an "encyclopedia" for it is that necessary, especially since the games themselves are just a variety of older ones (literally redesigns) and they have the simplest of rulesets. I'd say poker, blackjack and other types of card games would be the most complicated one and believe me, even if you didn't know jack about the terms, you'd still be able to play them.

As for sports, that's really on you. Not really gambling at that point, it's all about learning the rules of the game more than anything. And, well, yeah, AI exists. Can easily talk and ask nowadays really.
