People are different and never equal. Intelligence, education, seriousness, diligence, the chance to live in one place or another, and many other things make some people better than others, have a better or a harder life. Sometimes intelligence alone is not enough if there is no strength and willingness to work, sometimes you work hard for nothing if you don't understand the world you live in. Having all the qualities to be successful is very hard and only a few are the chosen ones.
I believe those who succeed should be happy with their chances and ignore those who can't. They are in different worlds...
I understand that you have been preparing for a long time, theoretically and practically, and you know what trading is and how it is done. It's a fascinating thing, I tried it without understanding and I lost rightly or I won by luck. I try to stay away... I'm glad you are so determined and I think you are also rewarded for it and probably will be even more rewarded in the future. I wish you that.
