There is definitely an edge to be found, but the game heavily favors players with structural (I am able to know things you don't) or institutional (I have hundreds of subject matter experts and deep pockets) advantages, and individual day traders have none of those things. Which isn't to say day traders can't get those things, it's just that you stop calling yourself a day trader and start calling yourself an investor when you start to intentionally build up structural/institutional advantages.
