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?
Definitely not. The way how they work is different from one another. If you'll understand the principle of gambling, it's pure luck based.
I would not agree with that principle, how can it be pure luck when some people are winning using their skills?
If it's a pure luck, people would not risk their money because in the end its the gambling sites that would just win since they have an edge.
Sports gambling is the biggest, there are bettors who bet on millions not because they believe they are lucky but because they believe they got skills.
Thus, there is really no professional here. You can't help yourself from losing in gambling if your luck isn't favorable of you but to stop. Meanwhile in day trading, you might lose continuously but you can be professional there with decent experiences and knowledges of course.
Everyone has different belief, some would say no professional gamble but some would believe there is because they themselves are professional gambler.
