Being a "professional" trader doesn't guarantee you any profits, that's not how the trading world works. There is an old saying that goes "The world's greatest swordsman is not afraid of the world's second best swordsman, he is afraid of the amateur because the amateur doesn't know what he should do, which makes him dangerous". A professional trader knows what to do, and what he should be doing, but could end up being wrong with one big piece of news, whereas a newbie could end up doing the wrong thing but because of that sudden news ends up making a profit. This doesn't mean newbies are better, of course, professional ones are better, it just means they lose as well.
