Please dont be deluded, you dribble far more than you head, and especially as a 'winger', you do it do drive up the pitch, to beat defenders to create space, create a chance for an other, create a chance for yourself. Headers depend on the cross, and Ronaldo only really uses it when he's in the box and the ball is at someone on the flank with the ball. That happens much less than dribbling, whicj happens literally everywhere on the pitch. How many of Messi's dribble have initiated a goal for him? Far more than the amount of headers Ronaldo will ever score or assisted (?)/ created or what ever. Because of Messi's dribbling, he can put defenders/keepers on the wrong foot and score so often, rewatch the match vs Bayern at Camp Nou for examples.
