There will be some people who will reject your assumption even though it is basically true, for people who are scientifically illiterate but very open to the name of profit they will not care about ideas that will hinder them. Many come because they are motivated by others who are successful and make huge profits from trading, they want to have the same fate but the problem is that they do not bring any preparation and fishing tools to get, isn't it nothing more than gambling? yes I would say that if anyone gets involved and enters the world of trading without having any understanding and knowledge, because they will only depend on luck.
With that said, I would agree with your statement that "trading is not for everyone", and I would add one thing "there is no instant wealth in trading". Before you jump in and get involved because you are motivated by the success of others then I hope you should first see what difficulties they faced in the process of achieving it, if you already know and have the answer then I'm not sure you will still be convinced to get involved. Basically, there are so many things you have to prepare, good planning, money management, emotional and psychological, patience, consistency and willingness to continue learning to improve. So think and consider again if you want to get involved.
That is such a terrible thing, same thing happens at gambling too, people see others win the jackpot and imagine what they could do with that much money and gamble and lose what they have too. Same at trading, surely there are plenty of people who make insane returns, but that doesn't mean that you can start today and start making a ton of money, you are going to end up losing money here and there, which is why you should avoid it if you could.
I believe that the best thing you could do regarding this situation would be just focusing on what you could do with what you have. If you are a newbie, then it is not wise to end up trying to do something regarding big profits, but trying to learn how to trade, that would be a lot better.
While learning, you could do well enough but that doesn't mean that you will be amazing, sometimes you will lose, that's normal while trading, don't be discouraged and hope that you will get better by working hard and studying.
