With experience and practice, one is able to consistently judge and achieve a rather precise aiming point.
Sudent pilots are required to be able to judge whether they are grossly under or overshooting.
Noting the aiming point is not where the wheels will make contact with ground, there is also some judgement at play managing the hold-off before touchdown.
