What happened to your "pure dribbler" ?
Winger/forward will attempt more directly take on while midfielder will be more caution. Also i think the word "take on" is more accurate than "dribble" when it comes to stats.
Dribbling comes in many form, not neccessary just directly beat your opponent in one on one. Pedri for example is a fantastic dribbler but rarely attempt to beat his opponent.
That's ball carrying, ball manipulation and press resistance.
A Yamal is easily a better dribbler than a Pedri.
Beating opponents outright and getting past them is dribbling. What Messi did most of the time was dribbling. What Grealish does generally is ball carrying.
Wingers are wingers because they are elite at dribbling and beating players. The brief given to a winger used to be "beat your man and put in a cross". The brief given to modern wingers is "beat your man and get a shot or final ball off". Wingers are the best dribblers of the ball because they actually have to beat their opponents outright like Doku does.
Ball carrying: Kovacic, Iniesta, Modric, Grealish.
Press resistance: Verratti, Thiago, Moussa Dembele, Busquets.
People who excel at one of these skills are atleast pretty good at the other one. For example Kovacic has excellent press resistance.
