Nah. That's just a regular circuit breaker. GFCI circuits trip
when electricity goes "missing". Like when you take a toaster into
the bathtub with you, the electricity can come out of the toaster
and go into the tub water rather than staying in the wires and
circuitry where it should be.

You have the right basic idea. It gets even more spectacular
when you use a long, thin, extension cord. It could be 50 feet
worth of fire.'
A ground fault will often cause an overload too, but the GFCI
mechanism in much quicker and more reliably when it senses
electricity missing, than a crusty 'ol regular circuit breaker
would when there too much current flowing.
