That's like saying "lightning is much more dangerous than thought, because what matters is not your risk of dying, but the risk of any one of 30,000 people dying".
If the risk is "1 in 1,000,000" that means it's 1 in 1,000,000. People understand that doesn't mean it never happens. But it's orders of magnitude lower than their risk of dying in any given year, so it's factually negligible.
