I think you need to sign up first and then read the TOS from the casino itself. I'm sure if there's a KYC requirement, it would be based on standards. A just casino will never make their gamblers have a hard time playing on the site, especially when the time comes for them to withdraw their winnings. After all, we are still playing in a crypto casino, and although KYC is required, it should only be very basic. Same with the wagering requirement, you can read it there.
