Gambling will always give false hope, so don't expect more from gambling. I don't think anyone is successful and rich in gambling, except for bookies. Gamble just for fun and stop when you have to stop, if you do that it will definitely be better.
In my country the government has controlled gambling, they even prohibit gambling. If anyone is caught gambling, they will definitely be punished. In addition, because it is prohibited, gamblers in my country do not have legal protection if they experience fraud or other problems.
