Here's an insight that helped me: gyroscopic precession is the rotational analog of a circular orbit.
A circular orbit is when a linear force is applied orthogonal to linear velocity. The direction changes, but not magnitude (speed).
Gyroscopic precession is when a rotational force (torque) is applied orthogonal to rotational velocity. The axis of rotation changes but not magnitude (rotational speed).
