I agree with your opinion. In essence, gambling for entertainment purposes is more suitable for wealthy people, as they already have a lot of money, so losing a little at the gambling table will not have a significant impact on their assets. Generally, someone who only seeks entertainment at the gambling table is a responsible gambler.
However, if you can control your emotions well while gambling, always bet no more than your initial gambling budget, and can control greed, you are truly fortunate, as not everyone can do that—including myself. The hardest thing for a gambler to do is to stop when they are winning.
We need to know that those who gamble are not only for entertainment. There are more gamblers who try their luck to win bets. It can be entertainment for the rich, but not for those who really expect to win. Not all gamblers can be responsible for the gambling they do, not only those who come with small bets. But those who are rich with big bets can also be irresponsible.
I agree with those who consider gambling a way to have fun. But those who have that point of view have they really considered gambling as entertainment, or are they just hiding from the fact that they are actually addicted?
