Your not wrong, just looking at one side. The 2% probability is like each person rolling a 100 sided dice. Roll 99 or 100 and you die, if 10k roll...you may get 0 or you may get 100 deaths.
Correct me if I’m wrong. The survivability rate is 98% which means each individual has a 98% probability of surviving. Not 2 people in 100 will die. 10k people in a room diagnosed all have a 98% chance of making it, which means all of them more than likely walk out fine.
