If he is used to gambling every day, he will feel that something is missing from his day when he cannot gamble on a certain day. And that can make him sad or disappointed or other negative feelings. He needed other activities that could take his mind off gambling.
He couldn't gamble every day. He also didn't know when he would be able to win so gambling every day could make him lose a lot of money.
It's the same as a big addict. Usually things like that have become their daily diet. The addict doesn't care about himself and even prefers to sit all day on the gambling bench, so it all depends on how much money he has to gamble every day, after all, only people have money. There are quite a few people who often gamble than entrepreneurs or established people, because their mindsets are very different so, in conclusion, people like that are mostly from the lower class, not from the upper or middle class.
