Why does the oxygen level in the air doesn’t change dramatically, when most of the trees shed their leaves in the winter?

Answer 1

It does. There is a ‘peak’ around August and a ‘valley’ around March. The thing is there is A LOT of oxygen in the atmosphere, and plenty of things that make it besides trees, so the variation is like 0.01-0.02% of the total atmosphere. In other words it isn’t something you notice outside of some pretty precise measurements.
