I know that electricity doesn’t just dissolve in the ground, it must return to the power source. But once the electricity is in the grounding device, how does it find its way back to the substation if it can be relatively far away?
Edit: I know ground isn’t used in normal working mode and where I live there’s no grounding in sockets.

Electricity doesn’t simply flow from source through circuit back to source. Electricity is defined by a potential difference. Electricity flows from high potential to low potential. Earth is simply the lowest potential available. It gives a reference as to what some voltage even means, because this voltage is in reference to earth.
I recommend looking up earthing systems, because this gives a rather good idea what earth ground is actually used for and why we ground circuits.
