No, the vast majority of courses only use ATAR for selection.
For those that don't (mostly medicine, scholarships or if you are applying as a talented athlete), they would probably only care if you were presenting athletic prowess as an extra curricular activity/talent of yours that was applicable to the program/scholarship you were applying for in some way.
Even in that situation, I suspect anyone in that position would have better things to talk about than school carnivals.
