I don't think so in gambling games for me it is everything about luck, maybe some short time of time you will have luck, win something and make some money, but in long period of time i don't think so, you can start losing and you can't live from gambling 
I can say this is true. The gambling depends heavily on luck and luck does not give you the assurance that you will always get it. You'll get lucky once in a while, but you will not always be lucky. So if in the short term, gambling can be profitable, but in the long run it can not be unless your luck likes you.
Precisely, there is no way that gambling could be profitable in the long run, most of the gamblers are losing and it they are going to continue it then the amount of money that they are going to lose in the long run is so big more that they could ever imagine. Thinking what's the future awaits for you in gambling could help you to realize something good.
