True enough! Still, I can't imagine a billiard ball with tolerances like that. I've shot 1,000 games and a ball being .5% off would be noticeable.

Enough anecdotes! Let's get to evidence. Leaving in a few to hit the river, but this looks really interesting for when I get back:

Other sources agree, the ball's .005% spherical tolerance is an order of magnitude tighter than Earth's. However, haven't read the whole thing, gotta go.
