Hey there!
There are two parts of the solar system: the terrestrial planets and the Jovian planets. the terrestrial planets all have surfaces, while the Jovian planets are all gas giants. They are separated by the asteroid belt.
The fact that they are separated by the asteroid belt indicates that Jupiter does indeed indicate that it lies on the outer region of the solar system. Additionally, the fact that as I stated before, it's a Jovian planet indicates this too. This is because, as aforementioned, all Jovian planets are in the outer region of the solar system.
Hope this helps!
