The one thing you're supposed to minimize as well as possible is "luck" in trading. Do you think it's always the same guys profiting the most yearly results of good luck? Absolutely not. They're the ones who know how to manage their trades when bad luck occurs and something unexpected happens. Luck has very little to do in long term trading career, i'd go as far as say it has absolutely nothing to do when looking at people with multi-decade long career in trading stocks/crypto/etc.

One of the best things a veteran traders has told me was "If a trade is not self-evident, i will not take it. The idea of studying charts is ludicrous to me".

Only takeing trades that you're sure of does pays off in long term.
