I have to agree on your point. While gambling also entertain us, but majority still gamble to make money, and you won’t expect for millionaires still aim to make more money as they have it already. So what they are looking for is purely to have fun and relieve theirselves from stress, and once they get over it, they will not gamble more often, hence they are not prone to addiction.

But for low income earners, they gamble to make money. But the more they gamble, the bigger the losses they’ve been acquired. Eventually, if they lose their self-control and discipline, then gambling addiction will follow.
