In my opinion making cash from gambling is not a good option and the statistical probability that you will win every game at every casino is very low. I think winning or losing every game is completely in your head, so your individual tricks are not there. However, we all have some kind of luck so we should strive for what is possible for us.
It is true that our winning or losing is influenced by our mindset. But it takes no tide, that our thinking can never bring our gamble in our favor. Whether one likes it or not, it is true that fate does not always favor everyone. It is not a reliable road to get rich overnight.
