are they the words for the same thing? When we say ‘connect to ground’ does that mean the same as connect it to the negative terminal of the battery?
Or do we connect a ground pin TO the negative terminal of a battery. Such that if we have multiple devices, and we connect them to the same ground pin, all the current can sink into the negative terminal of the battery? As it should?
MAINLY IN REGARDS TO ARDUINOS.

On a car, yes. The negative terminal does connect to the car body/chassis so any electronics can also connect to the body/chassis to complete the circuit without running a separate ground cable. Sometimes there is a separate ground cable, but it might even be shared between different things
