^^^It is just a like trying to get a right answer when you are asking the wrong question in my view. The OP speaks about poverty and gambling, which is already something of a red flag. Gambling is only for fun unless you are a professional player - e.g. a Poker professional, which is usually not the case if you are poor since you will probably have not money to play and not that much free time to do so.
When one plays gambling for fun it does not have much effect on him but when one chooses it as a profession it causes him a lot of financial loss. Because the more serious you are in gambling and the more you panic, the more you will lose. So of course gambling can make someone poor. But it is not very fast. A person gradually increases the amount of gambling as he gradually becomes addicted and gradually loses his wealth.
Yes, playing gambling for fun will always be recommended because gambling is not for making money. We can not resolve poverty problem from gambling but that can make someone bankrupt fast.
When a poor people playing gambling, he must know that he can lose all the money he have and that will makes him can not fills his daily needs.
Even if he is a pro gambler, he does not have to use gambling to makes money. He will not know when he can win from the opponent so it is better he have a job that can helps him to earn money. He must remember that gambling can make him poor and not have money at all.
But unfortunately what you said is a useless thing to say, why is that because all addicts do not care about the nonsense they prefer to waste their money on gambling, because it is one of the things they have to do and the rituals they have to do no matter that they are people who do not have much wealth, at least they can play calmly and not think about their daily lives they can even forget their wives and children.
Gambling is just a mirage can be dreamed of but difficult to express and a mere dream and a big dream in the mind of an addict, there must be someone who can change the mindset of people like that if they really want to do good things otherwise he will always do that with his daily life.
