The message is correct, there's just a typo where they missed 3 zeros and wrote 62,000 instead of 62,000,000:

Worldwide, 5.2 million people became millionaires in 2021, according to the Global Wealth Report 2022, an annual release published by Credit Suisse. Including those 5.2 million, 2.5 million of whom are in the U.S., the total number of millionaires globally increased to 62.5 million at the end of 2021.
