For "entropic gravity", gravity is not a force but a result of the desire of things wanting to go to a lower entropy state.
For example, if you release gas into a room, it will quickly expand to fill the whole room. The atoms of the gas are not being pushed to fill the entire room. The 3 quantum forces (strong, weak, electromagnetic) barely act at those distances. Instead it it is caused by the atoms randomly going around and avoiding each other. So no force forces them to expand, just their desire to be at a lower entropy state.
Another example is rubber bands. When you stretch a rubber band, the force pulling it back is caused by the entropy of the atoms. They don't want to be stretched as it increases their entropy.
With "entropic gravity", the idea is that things with mass actually want to be near each other. That is their lower state. So, there isn't a force pushing them together, it is just where they want to end up and they don't want to leave.
