I agree with you. Good traders make money most of the times because they have an understanding of the market. Unlike the majority of the market players, those traders don't usually focus on the top 100 coins but on those hidden ones down the list that are most often pumped and dumped. It takes skills to actually make good money as a crypto trader.
That is not far from the truth. The market is not for those with layman knowledge of crypto trading. I tried trading when I joined the industry newly and I lost more than 70% of my trading fund within a short space of time which forced me to pull out and commit to learning about the market and cryptospace in general. Trading is not for newbies!
