i'm always surprised how people here downvote correct information. This is 100% correct because heat in electrical wiring is a function of power (current) and time. The vast majority of electrical devices in a typical home use under 80% of their rated power. The few that do use their full power, like a resistive heater, often do not run continuously.

In contrast, it is completely normal to charge an EV at a socket's maximum power for over ten hours straight. This time component is why charging EVs from a regular AC outlet can be a fire risk.
