Yeah, pretty much. Generally the breaker will trip before the romex in the walls overheats, but if you plug in an electrical bottleneck that isn’t rated to what the breaker is it can fail and start a fire without the breaker ever being the wiser. An example is those ass multi-outlet extension cables made with lamp wire, some of those only do 10 amps or less before the wire starts glowing red hot.
