Playing dice is also a kind of trading but with negative edge (core argument). You can argue the same for any casino game with negative EV that some will win and some will lose, but the real question is can you make sustainable income from day trading, answer is NO, the math is not on your side.
Yes, there will be occasional winners with longer winning streak, just like in casino, but overall population will make a perfect bell curve as per the odds (which are not in your favor.)
