Potentially yes you yourself could become the circuit, but that would mean you would be standing bare foot in a pool of water, thus grounded, yet in our application, voltage would have to be a bit higher, and maybe amperage as well. Technically look at the electrons in a mod flowing as an army of ants, which path you going to take most often, exploring down the long road to the ground (down your hand, arm, body, leg, to foot) or the shortest route back to the ant hill?? You have a valid point you do, but there are so many variables here in the circuits you are talking about, hertz the circuit works at compared to your hand and body, voltage, amperage, environment conditions, fillings in your teeth if metal, the list is long. Basically look at the battery in your mod as an aircraft carrier, the electrons moving through the coils and mod and circuit are F/A18 Hornet Fighters, the Hornet is going to return to its home aircraft carrier most times unless ordered to divert or need to divert, their patrol flight path with be the same most of the time, returning back home.
