There are still some no KYC casinos out there but I myself am not really sure if they are trustworthy and completely safe to use.
But if we study and research more about the gambling industry, we can conclude that in the future more casinos will implement KYC due to license requirements and security reasons from casinos to avoid problems like money laundering.
I'm not that confident about it. From what I've read, casino licenses provide no protection against such things. One of them in fact does not allow the casino to serve its own residents. If what I've read is true, most casino licenses are just a cash grab from the government so that they get more money from gamblers, while basically offering little to no protection to their users[1].
I also don't think they care much about money laundering until a government asks them about it. Even if they don't require KYC, I'm pretty sure they store some data that is useful for investigators. Probably not a good idea to judge a service like a casino solely on their license.
