So basically, plywood does not expand as much as solid wood?

No, it does not ... however, and lest you think plywood does not expand and
contract with temp/RH changes, try laying a plywood subfloor without leaving
expansion gaps between sheets and the walls, then stand back and watch it
warp, wave and buckle over time.

That said, the dimensional stability/instability of plywood is going to be
an insignificant factor for your project.
