I keep seeing a load of YouTube videos and articles pointing out the cosmic background radiation and that we can see the oldest light in the universe etc, but isn’t that relative to earth’s position? If we used a telescope like James Webb from say, an exoplanet in a completely different star system, would the the cosmic horizon would be further out or closer in to us?
If we say the universe is 13.8b years old, would that number only be in relation to the position of fhe observer?

Yes, the edge of the observable universe is relative to your location. If you were billions of LY from Earth, a slightly different volume would be visible to you.
