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?
I'm not sure I see your point
Typically, short-term trading is compared to gambling, but a reverse comparison doesn't make much sense. It goes without saying that the longer you gamble the more effect the house edge has until luck becomes completely irrelevant (read, you are set to lose). There are loopholes that allow you to stay in profit overall when gambling and being a blind contrarian won't change the fact. But with short-term trading there are many more such "loopholes", so trading should be preferred over gambling, all other things considered and equal (read, you know how to trade)
