...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.
If you liken trading to game of luck then it is no different than gambling because gambling wins depends very much on luck but trading requires learning the skills and the better you become the higher chances for you to make profit from it. Although we cannot totally remove luck from trading because traders are predicting what can happen in the future which is not certain. But if you understand technical analysis and fundamental analysis it will be easier to predict and make profit, so trading is not something that anybody can rush into. If you have the patience to endure and learn how to trade you will understand that the delay is not denial and failures along the way doesn't define you.
