I'm confused
I am not sure what role you play at the casino, but presumably you have the power to bar someone who is playing with an advantage, and it sounds like this might also be one of your job responsibilities (just guessing here).
If you honestly think that he is not just lucky, then he has an advantage over your casino (legal or otherwise). Why do you care what he is doing? Also, why do you choose to let him play? I am very curious in your thought process behind this decision.
