And most of the people I see are those who can't control their gambling habits because they expect too much, and that's what makes it difficult for them to finally get out, at least take a break from gambling.
I have an acquaintance because I like to hang out with the same people, even though we're not very close. Every time he's going to gamble, then every time he says something that smells of very high expectations. Actually, that's not wrong, because I also sometimes hope like that, but the problem is that his expectations are too high in games that are based on luck.
There is a proverb that is "Greed leads to sin and sin to death".
Most of the time it is seen that greed is found in those who cannot control their mind. Sometimes it is to win a lot of money by betting to win more money and sometimes it is to invest a money which is lost in the bet to recover that loss in profit or loss. Repeated investment of money but later it is seen that the amount of his loss has increased.
And to be honest, the number of such gamblers is more in the world of gambling. I think gambling is not bad until a man can't control himself and bets beyond what he can afford to lose.
Yes you are right, it is not bad for people who can limit their gambling and only gamble when they have more money to lose. But not for people who force themselves because they hope for something that is unlikely.
There are some people who can win very large amounts from gambling, but what percentage of all people who gamble? I don't think anyone can answer that, and if we did, our answer would be only a small part.
