Gyros

I'm studying the AHRS system for a turboprop and learning about gyros at the moment.

The AHRS is described as a strapdown system and the gyros are described as rate gyros.
So to me this means that in each AHRS unit, there are 3 gyros, one mounted on each of lateral, longitudinal and vertical axis.
Each gyro doesn't move? So it just spins on its axis and the rates are calculated... somehow... I tried finding info on rate gyros, but there isn't a lot out there unfortunately, so could someone please give me a rundown on how rate gyros work exactly?
Also, how can rate gyros be subject to drift, acceleration and turn errors?
