Strength and conditioning matters in everything. Even if a weaker person has enough strength and stamina to complete a certain task, a stronger person performing the same task will be using less of his strength moving his/her body and therefore have more energy free to dedicate to other body processes, for example balance and even thinking and concentration. Of course weaker people can still 'beat' stronger folks, but the weaker person must have some other advantage in order to do so (better balance, better technique, better concentration, etc.).
