It’s not ridiculous. It means that by 2044, estimates are that over 50% of the population will be part of a minority group, and the largest single group (whites) will no longer be a majority of the population. The minority groups will individually still be smaller than the largest group.
This is a very US-centric view of things. Worldwide, whites are the smallest minority, and they are the only group to be shrinking. The largest group is of course Asian.
