Why your home’s (120v 15 circuit) does not overload tools that only use 1 amp, 2 amps, 3 amps (etc. anything less than the 15)?

Question

For example if I connect a 90v motor to a 120v battery source doesn’t that overheat and blow my motor?

Why is it though when it’s 120v from the wall then the motor is still fine?

Electric current is pulled by the tool rather pushed but the electrical panel. A 15A circuit means it can deliver up to 15A when a tool is plugged in but when there is nothing plugged in the circuit is at 0A.
