This is a very good question actually, and the truth remains that gambling is not actually meant for everyone, I can tell you that many today who are gamblers are supposed to not have anything to do with it due to their lack of boldness and strength to deal with a loss in gambling.

Gamblers ought not to be afraid of loses because this is something that is very normal, but this does not mean that one should not or ignore the need of only risking what they can afford to lose, so who ever is afraid of losing money to gambling shouldn't be gambling, because one day, they may risk money they know they aren't or can't afford to lose, and then end up losing it, this may lead the person to suicide.
