There is people who really make money from gambling but the number will not too big because gambling is not a way to make money. But people tends not care about that and still trying to make money even if they already lost their money before.
They don't realizes that gambling is not a way to solves poverty but will makes them bankrupt faster than they can imagine. People can not saves their money because they think they can make more money from gambling.
It needs more awareness from them not to use gambling to make money and search for the other ways which will be more possible to make money. Gambling should be controlled by the government but the government must warn their people not trying to playing gambling excessively to prevents the big lose.
Basically, gambling is not a way to make money because this is a business that is developed so the host also has the aim of seeking profit and even though they will provide benefits to players I think it is only a small part of the profit they get. Besides, I doubt there are people who can actually make money even though the amount is low if it is obtained consistently. Wrong behavior makes them themselves poor along with the wrong mindset such as thinking that they can get money from gambling, of course that is a wrong idea.
Everyone's awareness is there but it is not certain with the time, maybe some people realize for a long time that gambling is not a way to make money and some people realize it quickly, in my country the government warns people to stay away from gambling but it does not have a big effect because in reality there are still many who gamble until now until there are cases of bad impacts, so in my opinion this is about awareness from yourself not from others.
Gambling or casinos are very profitable businesses, and only benefit bookies, not visitors or players, because those who benefit from gambling or casinos are visitors and only a small portion of visitors benefit. And the small portion that benefits could be their lucky day but not necessarily tomorrow, and there are no gamblers who always win continuously, even those who are experts, and whatever the reason they lose more than they win.
Gambling continues to grow, especially online gambling which continues to grow and is also popular because it is easy to access, easy to get and also easy to see which makes people curious and finally open it and get involved. And the government in this case also plays a very important role and in my opinion they have also done it, it's just that one dies a thousand grow. And maybe there is also a government involved, and this problem is difficult to overcome and the only way is as you said, namely self-awareness and knowing the risks that will occur if involved and playing with full awareness so that gambling does not control you and also play with full responsibility only for entertainment or fun in your spare time.
