Not quite. The yaw rate sensor doesn't measure degree of lean, it measures how fast you are leaning. Imagine if someone put a spedometer on the surface of the coffee that measured the speed between that surface and the mug.

The name Yaw Rate sensor come from the naming conventions for the 6 degrees of motion, heave (sliding up and down), surge (sliding forward and backward), sway (sliding side to side), roll (rotating side to side), pitch (rotating forward and backward) and yaw (rotating side to side). Since yaw referrs to side to side turning, so a Yaw Rate sensor measures the rate of side to side turning.
