Panic about damage on the floor - Moving out

I’m moving out of my apartment and just noticed these small damages on the wooden floor. The floor was brand new when we moved in, and it’s real wood, not laminate. I’m not sure what caused these marks, but they’re visible under certain lighting.

How likely is it that the landlord will charge us for this? Has anyone had a similar experience? Would this be considered normal wear and tear, or should I try to repair it before the final inspection? Any advice would be appreciated!
