...because trading is also a game of luck and there's no one person that is perfect in prediction, just that when you are favored, it looks like you're the champion but I tell you that no champions forever.
Trading is more a game of skill than just luck if you like to describe it in the sense of a game. People who master this skill become better over time; their win rates improve with consistency and practice.
If you think of trading as a game of luck, you would never really put in the effort to develop the skill required to be successful in that field.
I agree with you on this point, I also pointed out this exact thing. If trading was based on luck then there would not be any need to run academy's or master classes on how to trade or become better at trading. Trading works with skills and it doesn't require luck to succeed. Traders that hope to get lucky are not professionals. This is actually a gamblers mentality and it attracts losses a lot losses in the long run
