The IJK describes the axis of the probe tip (the surface normal direction of the plane this probe would be ideally suited to measure).
The probe axis is shown relative to the current alignment axis. If, for example, you change your alignment so that +X travels straight up (replacing +Z) your probe IJK value will now be 1,0,0. The first IJK value is usually perfect because you are in the machine alignment.
The Angle is a 2D angle as seen from the alignment Z axis (I think). The reference axis is the X direction and CCW is positive. When you align a part that is not sitting perfectly flat in the machine volume your probe will appear to be pointing slightly in some direction in the XY plane and this is what the angle is trying to describe.
