They just do not want to pay, is that simple
I wouldn't conclude that too early, the casino wouldn't know a typical crypto player whether they are anti-KYC or not.
With reference to fully crypto oriented centralized casinos, I think as long as they have restrictions and comply with regulations will implement KYC eventually.
But why stating "no KYC for crypto"? And why you gyys tend to justify sportsbooks when they are being unfair?! It's a known fact that most of the sites love to scam you. I do not get these kind of things, really...
