Since the Sun has an enormous gravity compared to that of the Earth, does that mean that if I were to travel on a spacecraft similar to NASA’s Parker probe I would age much slower and if so, how much?

The Sun has a lot more gravitational pull than the Earth, this is true, but from a time dilation perspective it’s not very strong. If you were “standing” on the surface of the Sun your clock would tick slower than a person on the Earth, but only by a very small amount. I think it’s about a minute per year, or something like that. Not much. You need to start getting into the VERY massive objects, like neutron stars and black holes, before you start noticing anything too extreme.
