That is showing the raw numbers - they aren't adjusted for vaccinated/unvaccinated population sizes. ~53 million people have had at least one shot, and there are around 6 million children under 10 (so not counted in the figures you linked). With a population of about 68 million total, the unvaccinated all causes figures should be about 16% of the ever vaccinated.

The ratio should skew further in older age ranges, as a higher proportion of those were vaccinated.
