I’d like to hear from those who have actual experience, have you ever had a withdrawal blocked or delayed just because you routed it through a mixer? Or do casinos not care as long as your account is verified?
I don't have any actual experience with what you're asking, but I think it's best not to withdraw your money directly between casinos to mixer. I know this allows for increased privacy, but it also maintains privacy if you withdraw your coins to a new address before sending them to mixer. Casinos may not care where you withdraw your money, but other services may care where your money comes from and they delay crediting it due to violating rules or terms and conditions.
