Space is about 100 km up, on a sphere that has a radius of 6000 km, so some 2% is air.

A pool ball has a radius of 30 mm roughly, so 2% of that is 0.6mm. Seems like a very thin coat of paint to me, but roughly correct.

A coat of paint is like 0.045mm thick

Not on the walls I've painted. I don't know about pool balls, but I'd imagine they need a solid layer of paint too, otherwise they'd flake in no time with the abuse they get.
