If you know some real traders who are living a good life, then that proves that traders could be making money in the market constantly. With experience and expertise they develop in trading, it help them to become profitable in their trades. However, there could be uncontrolled losses but as long as they make more money compared to the amount of their losses, then that’s good to say that they are still doing well in trading, financially and emotionally.
You are probably talking about public traders, because there are traders who do not show their results publicly, that is why I think we do not see all the statistics regarding the number of successful traders. I also think that most of them care about their privacy in order to remain invisible to others. Money loves silence, you need to remember this and it is better not to show off your successes, because I very often see stories about extortion from scammers.
There are traders decide to do that, but actually not all traders are the same as what you have said here. Since there are some traders show their result maybe just to flaunt their gains and celebrate it. We can't also deny that there are people choose to hide their gains since they don't want to get disturb since we know there are so many people creating unnecessary commotion that provably can disturb those people who want to remain silent and secretive on their trades made.
If they see someone offering a certain like to good to be true offer then usually and say something that they can bring a passive profit to them if they invest or let them handle their trades since for sure they are dealing with the scammers so better avoid people offering a to good to be true schemes to them.
