Gravitational force is never truly zero. If it has mass, it is pulling at you, though it may be so close to zero that you don’t realize it.

Eh. It’s not really a definite distinction. Even in GR you formulate effective potentials and the gradient on those potentials are still called forces. Then, what is a force on microscopic scale? It is the exchange of force mediators, like photons. If gravitons exists, then there is even a similar framework for defining a force on a microscopic level for electromagnetism as well as gravity. Furthermore, electromagnetism (qed) also has an interpretation as a curvature, as it is a gauge theory, just not a curvature of physical spacetime, and that does not disqualify if from being called a “force”.
