I don't think so. I have the impression that the introduction part was talking in general, mainly because it says The amount varies by location and local wage trends, and then it talks about the US, specifically.
Appart from that, in page 23 of the Global Wealth Report 2024 by UBS in The global weath pyramyd 2023 it also says saomething similar, that 16.3% of adults have wealth in USD of 100k to 1m.

Did I get something wrong?
Edit: At the bottom of the investopedia article, they have the sources and since they only have references about the US, I believe I can safely say that I my assumption that the intro was talking about the entire world was wrong.
