Maybe mental disorders only occur when he is at home, and we don't know what factors influence it. But when he entered the gambling table, he was like a normal person without anything silly he did.
Is there anyone like that? because, if he doesn't have a stable mentality at home, how in the casino can he be a person who has the mentality of a normal person? I know, sometimes problems come from the family, which makes the person uncomfortable at home.. but if this person gambles, then loses, can he control his emotions because at home he has been known to have a mental disorder? This is something new for me, maybe you can explain it specifically, and do you know anyone who has that kind of mental character IRL?
