I’ve tried looking it up on Google but it’s all way too technical (At least for my understanding, yes I’m slow).

The root concepts behind all this stuff are energy (measured in joules) and electric charge (measured in coulombs).
Once we have those, we can describe the items you ask about (using the simple case of DC)…
Amperes: this is a measure of the electrical *current* i.e. the rate of flow of electric charge. If a coulomb of charge flows past a point in one second, that’s a current of 1 Ampere.
Volts: this is the amount of energy carried per unit of electrical charge (volts = joules per coulomb).
Watts: this is electrical *power*, which is the rate of transfer of electrical energy. This is the amount of charge flowing per second, multiplied by the amount of energy carried per unit of charge. From the previous two definitions, this is the voltage times the amperage.
