The motion of everything in the Universe besides light can be described in this way.

The people are moving much slower than the speed of light so the ground acts as a frame of reference.

As long as the frame of reference is stationary, all motion can be described in this way.

If one object is moving much slower than the speed of light, its speed can be added to that of another object.

The correct response is:
As long as the frame of reference is stationary, all motion can be described in this way.
This statement accurately reflects the principle of classical mechanics where relative motion can be analyzed using a stationary frame of reference, allowing us to combine velocities as we did in your example.
