I see that China is growing a lot in Steam according to the charts, which match what Valve say that China is growing a lot in Steam and what the market analysts say about China being the biggest and the fastest growing country, and that also matches with the growth in PlayStation.
These graphs you show can't be April and may 2023 becaue English would jump from 22.83% to 35.91% but says that the change is only +0.27% instead of +13.08%. Also, around half of the Steam users speak Chinese, so English can't be the top language, something is weird in that screenshot.
