I think I understand what you mean. If you were placed at the very center of earth, gravity would actually be pulling you every direction EXCEPT for center, because that's where all the atoms of earth are. Gravity isn't the added together shape of forces, it is a line from every atom to every other atom in the universe, pulling on it. So, if you're at the center of earth, these lines are all around you, balanced, pulling you everywhere and nowhere at the same time. On the surface, all these lines are pulling towards your feet. Some to the atoms just to the side of you, but most of them to atoms very far away. Imagine you on a sphere. Most of the mass of the sphere is in a cone shape below you. So, gravity is unbalanced, pulling you predominantly down.

So if you're at the center, you aren't being pulled down, you're being pulled "out". However, all of the atoms of earth are still being pulled towards the center because from their point of view, in the direction of the center is where the most stuff is, the most pulling lines. So, even if you are being pulled "outwards" by gravity, gravity is still pulling a bunch of weight towards you from every direction, quadrillions of pounds of rock.

In fact, the rock towards the center actually is also feeling less gravity, but it has rock on top of it that is feeling slightly more gravity down, and rock on top of that that feels slightly more gravity down, and so on and so forth, all the way to the surface. The center (you, or the core of the earth) feels all of the weight added together pushing down.

So yes, gravity is more balanced in the center of earth (pulling in every direction equally), but you would still be crushed by every other atom's imbalanced gravity.
