Risk management is most important thing in gambling sector. If you are not able to manage you risk then you have to suffer a lot after playing gamble. Because new gambler don't know actually risk management they play as a new and when they faces losses that time they suffer. Risk management is most responsible think in gambling sector because no one can't be an successful gambler without it.
I think when it comes to gambling, it is hard to have risk management as everything relies on luck. It is possible to reduce the risk by just simply analyzing, the knowledge, skills, etc. If that is the case it would be stressful in the long term in gambling as everything you would need to identify everything for you just to profit. Well, even famous people who invented formulas in probability and statistics use them for gambling just to profit like for example Pascal. It is indeed a must-cause if you are just impulsively betting your money without thinking of any ideas, for sure you would just pray for your luck to be on your side which is rarely to happen in gambling.
