Do I need a turntable amplifier if I have powered speakers?

This may seem like an obvious question, but I’m new to “home audio”. After being fed up with MP3’s, I’m about to jump into the world of vinyl. I have a really nice pair of powered studio monitors for home recording.

It seems like as long as the turntables themselves have power, and the speakers they are fed to as have power as well, there’s no need for an addition tube amp.

Correct me if I’m wrong here.
