I think it's sort of mostly true except when it isn't...
e.g. we infer from observation the expansion of spacetime at speeds greater than the speed of light/causality, and time gets strange when you have interactions/observations between multiple bodies at relativistic speeds, and things also get strange with various wormholes and singularities swapping space for time and time for space.

if spacetime is expanding - then does that mean the earth and everything on it is getting bigger

I don't think so.
The expansion evidently only takes effect in the absence of one or more of the fundamental forces - which are observed to be constant everywhere (even within the galaxies observed to to be receding faster than others). The expansion only affects the sparse space between dense regions of spacetime.
In order for us not to notice our own physical expansion all the laws of physics would need to scale up at the same rate, otherwise we'd notice the density of matter decreasing. Physics, chemistry and biology would all start to go wrong. Gas giants would start swallowing their moons. Your cells would stop working. It would be no fun at all.
