It seems to me that in physical casinos it is absolutely impossible to get into the casino using someone else's documents, because the people at the entrance are not fools and they understand perfectly well who is in the photo and who is in front of them.
Maybe you can't use the other user documents, but you could use someone else bank account. In my country when you go to the casino they ask for a bank card, if you make a profit the money goes to that bank account, so, you could get a bank card from another person and use that to gamble, And it's similar to the online casinos, if you win big then they could ask for more documents but if you win small amounts there will not be any problem.
