No, this absolutely does not explain the US's wildly off-base per-person expenditure because uninsured people still go in the denominator.

The fun part is when you break those numbers down between government and non-government expenditure. You’ll find that US governmental spending on health care per capita is higher than every other country’s entire (gov and non-gov) spending per capita.

		Could this be because US gov healthcare spending takes place mostly via Medicare, which is specifically for people 65+?

		In that link, government/compulsory for the United States seems to indicate times when an insurance company covered it. Voluntary/Out of Pocket is when insurance company wasn't required to cover and did or person paid out of pocket. Even if it's US Government only per capita with people the government insures, it makes sense it would be so high because only people on government insurance are the poor/disabled AND old. Two groups that have extremely high utilization.

		That number seems hard to believe? Specifically that non government spending would be this low. Presumably "compulsory" includes way more than direct government spending. https://data.worldbank.org/indicator/SH.XPD.GHED.PP.CD?locat... According to the world bank it's closer to 40:60 (government spending still being the majority). So that puts it behind Switzerland but still more than combined spending in just about any other country.
