Most modern grenades send tiny pieces of metal outward about 50 feet but the kill radius is about 15 feet. Various factors can play into survival of a grenade blast like barriers, distance, and grenade quality.
Based on the video the poor quality of the grenades saved lives. Only six people received severe wounds, including the bomber. The grenades were dropped at the feet of those in the room and lower limbs were at risk.
