Reach IMU Accuracy

I downloaded the datasheet for the MPU9250 but I am not an engineer. Can you please tell me what the accuracies are for pitch, roll, and heading? Many thanks

MPU9250 provides acc, gyro and magnetomers value; pitch, roll and yaw values are calcolated by algorithms and therefore it could be quite difficult to provide real accuracies. A lot will depend on those algorithms, and on sensor calibration as well.
