A rock doesnt decide to fall.
Thats the difference.
The rock is predictably going to obey the force called gravity.
Now, if I decide to walk over and pick UP the rock lifting it in exactly the OPPOSITE direction then there must be a (different) force acting on that rock which is opposite to gravity.
Furthermore, the force lifting the rock (me) acts unpredictably both in magnitude, direction and timing - unlike the force called gravity which by definition is constant.
