Those numbers for each cause are over the course of a year. The COVID19 Deaths are only over the last 3 or 4 months. Some may have had other underlying issues but if they contracted the COVID19 and passed then it will get marked as COVID19 related rather than the original underlying cause they had before the COVID19. No one will ever know the actual causes of their deaths since such a large amount in such a short time won't qualify for a date with the Medical Examiners Office.
The bottom statement is very true we don't live forever. There are only two guarantees in this life and that's Death & Taxes.
