ELI5: If there are fewer leaves in the winter, does it mean we have less oxygen then?

No. The global oxygen level do not fluctuate that much if at all from things like loosing leaves because half the world is always going to be in summer. Also equatorial rainforests are always in summer, and contribute the most of anything to filtering air.
