These are age cohort averages. If you die of COVID despite being vaccinated, clearly the vaccine was 0% effective and early treatment could possibly have helped. Either way, 70% is not incredible in my book. The 95% from the booster will not last.
You are confusing the outcomes of 'serious illness' - which you presented numbers for, and 'death'. Yes you are correct to say if something is effective 999,999 in a million, it is 0% effective in the 1 person. As you specifically mention deaths, but present no information regarding it here is the UK data: https://www.ons.gov.uk/peoplepopulationandcommunity/birthsde... All cohorts: 51,281 total covid deaths in the 6…
I can give you a source for deaths in the past few weeks in Israel, but only stratified between over/under 60:

The picture is similar: Efficacy of around 70% (two doses) and 95% (fresh booster) against death. This is far from "one in a million". If you age-stratified this data further, you would likely get better efficacy though.
