There are tons of the characteristics which will be deciding the profit level of one trader. I believe only the profits and the frequency of profit will be deciding a trader as a professional or not.

I'm not seeing only very few characteristics will be helping traders to become as a professional traders because if it is not that much simpler one then we will be having more number of successful traders but actually trading is not working in that way.

Making profits from trading is a highly challenging job and every trader is working hard for their personal profits and in this process they are finding themselves as a professional traders.
