in the end of the day it comes to users personal preference
maybe they'll have to sacrifice a bit of convenience and play on a DEX casino or even if centralized, without KYC
even if this means they lose the option to play some of the games or have smaller liquidity depending on what they're doing
There's no way someone will create a decentralized casino since this mean they're not gaining a lot profit due to decentralized, except they're asking a donation or someone willing to send more money than it does. Since casino is created to make the owner rich, that's why I say it's almost impossible, they're also need to create their own game without cooperate with other providers.
Many platforms use the term "decentralized" incorrectly, and so do casinos that accept crypto as a payment method. Sometimes they call themselves decentralized simply because users can use their personal wallets to access the games. Although these platforms have some level of decentralization, they still have centralized servers and middlemen that control your money and the operation of the platform. As for their profits, it doesn't matter whether the casino is decentralized. They can still set up their DAOs so that they extract significant percentages from every game bet, much like decentralized exchanges do.
