Yes, you’ve got the right idea. When a voltage source is connected directly to neutral with no resistance in between, way more current is going to flow through the conductors than they can handle, and things are quickly going to burn up.
This is the main reason we have circuit breakers. As soon as the amperage in a circuit gets high enough, the breaker for that circuit trips, cutting off the power supply and (hopefully) preventing any of the components from being damaged.
