You are right that we don't have much of an option for the time being since there aren't any authentic casinos that don't ask for KYC and lets you deposit, gamble, and withdraw your money all without submitting any personal detail, we can see a few decentralized platforms coming out but yet again, we can't just trust any platform that comes out because we know how saturated the market is and there are a lot of scams happening around.
Wrong. There are plenty of legit crypto gambling sites that don't mandatorily enforce KYC in any form whatsoever. Some of those sites off the top of my head are Crypto.Games, Bitcasino, Sportsbet etc.
These sites only request KYC when you are withdrawing large amounts or if they find something shady related to your account.
