It is difficult to compare numbers between countries as they don't all use the same terminology. It appears that in the US, any presence of the virus will count as a COVID death even if the person is asymptomatic and the cause was an unrelated condition, or even injury. Other countries will only count those that they can confirm were killed by the infection itself. It's really easy to get into a GIGO there.
Another major variable is that nobody really knows what percentage of total infections result in any interaction with medical care and are tested. Some health systems will only test someone admitted to a hospital, whereas others will test anyone presenting with any symptoms.
I keep in mind a saying that my grandfather liked to use - "Figures don't lie, but liars sure figure."
