The size of tidal bulges caused by movement of the oceans is maybe 50 feet maximum, a tiny amount in comparison with the polar vs. equatorial diameter difference of 26 miles. It doesn't affect the comparison of Earth with a billiard ball to any meaningful degree.well now that seems to be a point of controversy .. is the surface of the ocean = to the surface of the earth? if not... why not?
I only mentioned the tidal movement of the Earth's crust (less than an inch) because you brought it up.
