Not really. Grounding doesn’t do what you think it does. A gfci protected receptacle is much safer than a grounded outlet, even if the gfci protected outlet doesn’t have a grounded circuit. a 15 amp circuit is designed to trip or disconnect around 15 amps. Current over .2 (that’s point 2) amps can be lethal. A human body will limit current flow typically to less than an amp at 125 volts.
A body doesn’t allow enough current flow to cause a 15 amp circuit breaker to trip. You will be electrocuted and the breaker will never trip
