I always believe that gambling is not profitable in the long run cause the games are meant to take money from you so the owner, casino owner can make money from it. Otherwise why would they have casino in the first place.
It is profitable for those people who are already in that industry for a lot of years already. But for those people who are just new with it.
Then it is not going to be profitable and most of the people who are making big profits with gambling in long term are the investors and owners of gambling sites.
Very few people who are simply lucky that make it profitable in the long term.
As quoted most of the gamblers here were losers but they still continue gambling just because of the hope that they will win some day. When this hope turns to be greediness addiction occurs which paves path for complete loss. On this basis I believe gambling is profitable in long and short term when we fix limits and go for it.
I dont think so because it is use by script and bot. You know when you use script and bot it will the the house in the future. So no more money left in your income or in your profit. That is why it needs to be the way you like it if you want to bet.
Winning in long run is impossible just because of house edge. 
Gambling is not profitable, and might cause serious money problem in the long run for gambler, but still, we cannot deny the fact that there are also lucky ones who make their way out with big amount...
