We know that day trading or short time trading is like playing with wild fire, not may can handle it. That's y most player's end up in loss and very few are successful day traders.
Is that hold true for gambling also?
There are posts here that gambling is addictionand how to get rid of.
Are there gamblers here who are in profit overall?
Gambling, not equal to addiction. Gambling addiction in my opinion, is taking big risk frequently, or addiction to taking big risk. You can't easily control the addiction, usually because it makes you feel better, excited or good. This is why it's good to bet only little or what you can afford to lose on good/safe games.
