  The goal is roughly that if you manage to hit some of these numbers, it's because things have already gone catastrophically wrong. It's not feasible to ask for certain safety in all possible conditions. The only thing that can manage that is a bomb shelter with 50 parachutes.

  Per the FAA (https://www.faa.gov/regulations_policies/advisory_circulars/index.cfm/go/document.information/documentID/22680 https://www.faa.gov/regulations_policies/advisory_circulars/...), the actual number for "Almost Certain to never happen" is no more than 1 loss of life per 10^9 flight hours. There's a real number behind that term, but not necessarily a stat that's accessible to the average news reader.
