Actually, the super very best don't need to. When you play the nosebleeds and your entire player pool is Antonius, Ivey, Dwan, Galfond and another 5 or 10 players, you can depend entirely on your observation to keep track of your opponents.
Trackers become really important when your player pool has hundreds or thousands of players and it becomes physically impossible of keeping track manually while playing 1000 hands per hour.
