Most of the people that believed that they can make money from gambling are not yet rich, they are still poor, left in the same stage that they were for years now, is that not self deceit? Best way to go about gambling is to not have a very high hope about making money with it because such hopes has made some people poorer and frustrated some people, while some people also lost their life for it. Some people chase after gambling, leaving to do what's so important that can fetch them money consistently.
Yes, such beliefs will plunge someone into poverty, instead of wanting to get rich quickly, he will lose more and more money quickly. It is true what you said before entering the world of gambling, having a clear understanding and thinking about the results to get a big win is very difficult to do, in the course of playing time there will definitely be unexpected obstacles or obstacles and as much as possible we must be able to solve these problems carefully and wisely.
Instead of handling it as a means of income, it's much better to just handle it like as a fun activity because even while you handle it as fun and risk the amount of money that you can afford to lose, you can still be lucky on different bets and that would give you some profits, but when a gambler decides to be greedy by thinking they can win the casino and make a quick money from them within a short period of time, that's when the casino would prove them wrong, because the casino is also running a business that should be profitable for them much more than the gamblers.
