The reason stars don't appear to change their relative positions in the constellations is simply because they are so far apart and so far from Earth that any movement is imperceptible to humans due to the vast times scales which would be required to detect movement.
Precession doesn't change the relative positions of stars in the constellations; rather it changes when a given constellation will rise and set at a given time of year. So while the stars in Orion will still look very similar to how they appear now in 13,000 years' time, the constellation Orion as a whole will rise about 6 months earlier than it does now, due to the wobbling of the Earth's axis like a top (which completes a full cycle in about 26,000 years).
