oceansgate was a company making objectively shitty subs so they dont really count (imagine if some guy made a car from scratch and the engine blew up killing 4 people, its the same thing). you probably cant name a single other submarine accident. you can probably name people hurt by cars though, you probably also know a few in person.
subs are the same as planes here, if something goes wrong probably its a fast death for everyone involved but its also incredibly unlikely. basically, if you get total kms traveled and divide that by total injuries/deaths for both cars and subs youll see that subs harm less people per km
