No one has ever said this.
This is such a frustrating part of modern discourse which makes it impossible to have a proper national conversation.
WHO and governments say something like "the death rate under 40 is 0.012%" or that no one under 59 has died in the UK and then some anonymous doctors says "its not true young people wont get ill I treated ome last week!".
There will be people from every single demographic that die from this, but we're putting special precautions to protect old people because their chance of dying is 100x that of a 30-40 year old.
