Basically when a gambler keeps losing money by gambling, if you suggest to him that you correct your mistakes, he will never accept it, he will do whatever he feels like because he keeps gambling and losing money one after another. There are some gamblers who double their confidence if they win money once they gamble. Then they would earn twice as much money by playing twice as much, but they returned home empty-handed. Gambling is an addiction that slowly leads a person to ruin his life. There are families who used to live a beautiful normal life only when someone in their family is addicted to gambling, the whole happiness and peace of the family is destroyed. So gambling makes people's lives miserable so everyone should refrain from such gambling so that they can lead a good life with their family.
with those who cannot accept advice or suggestions from other people to correct their mistakes, it is because they are addicted to gambling, right? because in my opinion, people who are addicted to gambling will not be able to easily accept suggestions or suggestions from other people, unless they are aware of themselves, when they are aware, then they can accept advice and suggestions from other people whose aim is to correct their mistakes. It's true what you said, if they have become addicted, they will likely ignore the things around them, and they will only do what they like and think about, namely continuing to gamble.
In fact, gambling does not destroy their lives, but they themselves are the ones who are wrong in choosing the path, so that they experience many problems such as losing unreasonable amounts of money, as well as experiencing the destruction of their relationships with each other, or their own health. It's not right to blame gambling for ruining someone's life, because I think it's their own fault.
