That's likely theater. if real rockets / drones were fired, there would be 100x more people dead. There is almost certainly some "understanding" with all parties involved.
A more likely reason for the lack of widespread death in Israel is the Iranians don't have the capability to cause it. The Israelis have air raid shelters, plus early warning radars that give them time to get to those shelters. And they have anti-missile systems to take out the most dangerous incoming ordinance.
