I have no icdea where you got that 34% from but it absolutely does not at all match any mortality rates for this virus anywhere in any normal setting.

As for the elderly dying more than all others by far (including younger immunocompromoised people), the numbers are plainly available for a variety of regions and countries. They speak for themselves clearly enough.By far and away, the absolute majority of all dead are those over the age of 70. Most of them over the age of 80, and even those with what would normally be comorbidities among younger populations ide so rarely of Covid that they're outliers. Healthy young people are extreme outliers to the mortality count. Even in northern Italy at the worst of its saturation of the healthcare system, the same thing was observable: deaths among younger people are outliers across the board.
