I agree with you that making money from gambling is not a good idea. This is either not possible or very close to impossible. I'm not talking about victories and winning large sums of money. I'm talking about the original idea of earning money for a living by gambling. That is, when a person at some point begins to think that he is good enough to stop working and start receiving his main income from gambling. I think that this is not the best idea and most likely nothing good will come of it.
I don’t really understand what victory and defeat mean in your head. I think that some luck plays a big role in gambling or betting.
casinos are not a place for someone to be able to get money to meet their daily needs, someone cannot make gambling their job because it is just a pretty stupid idea considering that casinos have a higher chance of winning compared to gamblers, and because of that gamblers who want to make gambling their job to earn money every day will only be wasting their time and money because it will be very difficult to achieve, unless they have high skills in games that rely on strategy.
