In my opinion, I think anyone who can't bear the risk of losing in gamble should not even think of venturing into it. Because there's no point of being scared of losing, when losing is something that anyone can not avoid so far as gambling is concerned. No matter the knowledge one wish to acquire about gambling, definitely he can't even escape losing. However, gambling is not for everyone, rather is for those that are willing to accept whatever outcome they get in gambling. And also except the fact that gambling is purely based of luck, isn't what anyone can guarantee us about the outcome.
