In PPP (Purchasing Power Parity) they will, in real dollars China is forecasted to but India won't be close. As a US based tech company my customers pay me in real dollars so we use real vs. PPP for our market size analysis.
I suppose we could debate about if I'm paid in real or nominal dollars for my tech I sell to folks. Today I'm paid in nominal dollars, over my 10 years of history it's real ones.
The core point is I'm not paid in PPP dollars from India with a 17/1 PPP adjustment over the US.

In real dollars the US ($19T) still has a substantial lead on China ($12T) today so the 2030 forecasts assume continued substantial growth for China.
