There's a guy my dad knows who can't keep a simple beat. Tell him to keep a basic 4/4 beat, just cannot do it for the life of him, even with lessons. He's tried to play guitar his whole life, yet never gets further than a few simple chords, which he plays sporadically because he can't keep a beat. I believe talent is real, not in a "magical sense", but in a way that maybe some of us are genetically predisposed to do certain things others can't.
