The bias is the voltage output when there is no rotation. For a 5V gyro this is usually 2.5V nominal. WPILib calibrates the bias of the gyro as part of the constructor. Errors in this calibration, or drift of the bias point, result in drift in the signal.

The sensitivity is measured in mV/degree/s. Your calibration is at 0 degrees/s. How does this yield usable data about the sensitivity?
