Yes, those who can learn from the mistakes of others and realize the right thing will definitely be able to control themselves before the damage happens, but unfortunately not everyone does that. Many people do not realize it until they suffer the pain themselves. However, even if there is some damage, if they can understand the right thing and come out of it, then that is also good, because there are many people who do not understand the right thing even after the damage, after the damage they start taking more risks, and make more emotional and greedy decisions, due to which they face a bigger disaster. So I want people, whether it is from the mistakes of others, or from their own experience, to be able to realize the right thing anyway and refrain from making wrong decisions, because if they cannot control it in time, the amount of damage can be huge.
At the very least, if we can understand and learn from the experiences of other gamblers, we can prepare to anticipate worse consequences if we end up making the same mistakes. It's better if we can control and avoid mistakes, but if we can't, at least we can avoid falling as deep with the smaller risks we face.
There are many cases of addicted gamblers who have been destroyed by them, we can learn valuable lessons from them and try to avoid making the same mistakes.
