If you are asking is there anyone who is successful in trading and they consider trading as their primary source of income? I can say that, yes, there are many. But to do that, they also spent a lot of time studying and training and also lost a lot of money in the past. Everything needs trade-offs to achieve, it's not easy to do in a few days or a year or two, it's a very long and arduous process.
As a newbie, you need another source of income, not just trading, because trading is not always profitable for us. Only consider it the primary source of income when you have enough experience and are sure of your earning ability.
It's not about "is there someone out there you don't know about", it's about are you one of them, and if you are one of them then how did you do it. We can guess that there is at least one person, probably dozens even hundreds of people who make a profit from trading daily, but we do not know them.
If we knew how they do it, like if that person explained to us how they can make that happen, then we would learn and do the same. I personally do not make enough from trading to consider it a full-time gig, I do not make enough to consider it even a part-time gig. So I can't answer this question, but if there is someone who does, with proof of course, it would be great to explain it.
