Do Day Traders Really Make Money?

The question is, do day traders whether in stock market or in forex really make money?

Research suggests that most of the day traders do not make money. Probably only 20% of day traders will make money.

Surprisingly, studies also suggest that those traders who placed the most trades made maximum money, probably because they were the most experienced.

My addition is that those who took it as a hobby would have definitely lost money.
