Based on the wiki for WaMu, the numbers are not inflation adjusted. According to the BLS CPI calculator, $1.00 in October 2022 has the buying power of $0.73 in September 2008, when WaMu failed. 20.9b is closer to 15.3b in 2008 dollars. Based on the graphic in the post, it's still the second largest, yet half as large as the largest.
As a disclaimer, I'm not an expert and am unaware what flaws my analysis may have.
Edit: The values should be Should be 209b and 153b, respectively. The author of the article made a mistake in their graphic which showed the value of SVB as 20.9b when it should have been 209b. I carried this mistake over in my original post. The author has since updated their numbers.
