Many people come in gambling in order to win in a short time and change their faith. They are the ones who can't afford to lose. If these people lost in gambling, that would have a seriously bad effect on their lives.
On the other hand, there are people who have a lot of money in hand and losing is not a big deal for them. If they win in gambling, they enjoy and if they lose, nothing is lost for them as they have a lot of money in bank balance. They will come again next day and play more without worrying about the money.
So can we say that gambling is for the riches who can afford to lose?
Gambling never differentiates rich or poor, as long as they have money to gamble of course anyone can gamble, but even so of course there will be differences between rich people who gamble and poor people because indeed they have differences in capital and also bets in gambling, I think only in traditional casinos the rich who gamble will get more preferential treatment than ordinary gamblers, but this is not the case in online gambling and all gambling users will certainly get the same treatment.
About people who can afford to lose or not, I think both rich and poor of course no one can afford to lose, but I think rich people may be more prepared to lose because it is certain that they still have reserves of funds to anticipate the loss, while poor gamblers of course, losing money at the gambling table will increase their financial burden, so it's better if you don't have enough money or income, it's definitely better not to gamble at all.
