I think the best way to visualize it is that when you are inside a star, you are effectively "standing" on a smaller star. Everything behind you can theoretically be ignored. When you are very close to the center, you are standing on a very tiny star.
So instead of the hole density from one side to the other, I only have the density from the center to its surface, am I understanding that correctly?
I'm not sure what you mean by "surface".
Imagine you are standing on the surface of Earth, and you weighed 200 pounds.
Now imagine Earth were magically transported to the center of the sun, completely replacing an equal volume of solar core. Inside the very middle of the sun, standing on planet earth, you would still weigh 200 pounds. The gravity of all the solar mass surrounding the Earth would cancel out.
If you traveled upwards, to the surface of the sun, your weight would increase. At the sun's surface, you would weigh 5400 pounds.
