Gambling is about luck and I don't hesitate to try my luck and sometimes I get real lucky, while sometimes it is what it is 
I think most gamblers must understand how the concept of gambling is luck. but there are still gamblers who complain and even accuse casinos of being a scam because they never or very rarely give them wins.Gamblers take risks by betting their money on games. but some do not consciously accept that they are unlucky. Such gamblers should never know gambling, they will only lose more.
