what the hell is electric charge? Like it doesn’t make sense sense to me how protons are positive and electrons are negative like what does that mean?

In general physical reality likes balances so “things” as a vague and all-encompassing concept tend to move from locations with a lot of that thing into an area with not lot of that thing. Wind happens because air moves from high pressure to low pressure in an attempt to equalize. Heat energy moves from locations that are hot, have a lot of heat, to locations that are cold, or don’t have much heat.
Charge is one of those things that exists and moves from locations where there is a lot of it to locations where there isn’t. Movement of free electrons just so happen to be the way that charge exists. “Electricity” is the name for what happens when something forcefully creates a difference in charge between two locations and electrons move from the high concentration to low, just like “Wind” is the name for what happens when something forcefully create a difference in air density between two locations and air moves from high to low density.
If you wanna “Why?” at it beyond this point you start getting into the quantum mechanics stuff with the quarks, leptons, bosons, etc that tries to explain why the various subatomic particles are different.
