Which country is the wealthiest country in the world? Why do sources disagree?

by fishlord05

I saw many headlines claiming that China has become the wealthiest country in the world, overtaking the US by a huge margin.

Curious I also wanted to see if any other sources thought the same, so googling “countries by wealth” I came to the Credit Suisse ranking on Wikipedia which seemed credible

For 2021, it said the US dwarfed Chinese wealth. Why is this the case that they disagree so much? Is it the methodology? Who should I trust more? What should I make of this?

Thanks for your time
