I understand why you get harmed if you’re grounded, you’re becoming part of the wire and the electricity is going from you to the earth. what I dont understand is, why the electricity doesnt harm you when youre not touching the ground, isnt it going through you either way? how does it not affect your body?

Although it isn’t perfect comparison a lot of the rules for electricity also apply to water flow (like series and parallel resistance laws) where Pressure is the analog for voltage.
So as a simple explanation, take a water bottle and open it, now close it flip it upside down, and open it again.
When it is facing up there is no path where the water can lower it’s energy so it doesn’t flow, when it is upside down, the water flows out because there is a path where it can lower it’s energy.
Also electricity doesn’t really take the path of least resistance, it takes all paths wieghted by the resistance of each path.
Basically as long as there is no voltage difference electricity won’t flow. Which is why a switch works
