And some cat5 cables will take gigabit speeds even though they’re not rated for it if they’re high quality enough too.

Cat5 is rated for Gigabit over spans of up to 100 meters.

The 1000Base-T spec predates Cat5e.

Especially if the run is relatively short (<=100ft) and it doesn't run parallel to noisy power cables.
