Does jumping on a grenade actually save people?

Yes. Grenades aren’t that powerful. And the explosive force they generate is largely to break the grenade shell up into fragments/shrapnel, which actually cause injury. Jumping on a grenade is near certain death, but also pretty certain to prevent injury (certainly serious injury) to others nearby.
