He doesn't understand himself either... I am pretty sure about that. There's something about provably fair games (in-house games that can be verified by the third party), but winning probabilities for slots and some live games depend on the provider, and their RTP is usually visible, but we can't verify our bets. I guess he mixed up those two... somehow, some way.
This is something most of us from here understand... but for people outside crypto all this looks like a "spaceship"! After so many years in crypto, I still make mistakes here and there, especially when I am trying out different possibilities, and in crypto, we sure have a lot of them. If we talk about crypto in general, including all coins, tokens, and chains. Wallets are a different story, but very important as well...
The headline is simple "The Rise of Crypto Gambling: What You Need to Know"! The first thing is definitely setting up a wallet, but only one wallet will not do much if you wish to experiment with "all the possibilities in the crypto gambling space". And people should really be careful with using "the right chains and addresses"! You can't believe how many people make those simple mistakes, and for newbies all that can be really confusing!
