Who are in your opinion these ∼1% of traders? Why they are able to remain profitable? Are you sure you are one of them, if you include taxes, fees, etc.? 
I believe that the percentage of successful traders in the long term is more than 1%, ~ 5%. In the long term, very few strategies have the right to exist.
In the short term, the number of successful traders is much larger, especially in the interval of 3-6 months, sometimes their strategies bring big X's, but in the long term they cannot maintain profitability due to psychology and loss of concentration, in my opinion.
Who is this 5% in the long term? Well, if we discard all market makers, traders from hedge funds or banks, and take into account only retail traders, then these are the traders who have balanced risk management and money management close to the ideal. Although there is no limit to perfection.
