How does electrical ground work? Why does electricity want to travel to the earth, which doesn’t seem particularly conductive?

Question

Some additional questions I have to further understanding:

Ships don’t have ground, but why couldn’t electricity on a ship ground to the ocean the same way houses ground to the earth?

A structure will have a grounding rod dug into the earth. Does the dirt, soil, and rock composition that the structure is built on affect how willing current is to use the path?

Ships ground to the hull. Either electrolysis or galavanic reactions will occur, which is why they are fitted with sacrificial anodes.
