The true 5% of traders that are very successful and profitable do not even have a YouTube channel (only a very few exceptions). They are strictly for trading only, day in and say out.
This has also received attention from me, if a YouTuber really makes big profits from trading then why do they create a YouTube account about the basics of trading or about trading because it doesn't take long to become very skilled as a trader! returning to the discussion about what actually produces results for youtubers, it is advertising, so the goal of a youtuber trader is only to get money from other sources.
So we are talking about the time to become a professional trader. If we want to become a professional trader quickly then we also have to increase the hours to practice directly on the exchange. We also need a lot of money to do that. Meanwhile, content creators can sometimes collaborate with several parties to get additional capital that they can use to practice.
