In everywhere but gambling, the risks you take should be the lowest because gambling is brutal, you will get hurt easily I advice everyone not to depend on gaming as a source of income.
It's better to rely heavily on your job and make sure you have a job before you start to gamble, the absence of income is why many gamblers turned begger, many of them end up with debt they can never pay back.
Good analysis is required before placing a bet, this spikes your chances of winning the game but it still doesn't guarantee that you will win.
