A big part of the numbers game is on variants though. There's what, eight or ten total RP2040/2350/2354 parts to choose from? So all the volume is split between those. Conversely, there are a lot more variations within other MCU lineups. Just looking at the WCH CH32v30x datasheet-- a single relatively low-popularity range from a single vendor, the datasheet shows 9 basic models with five different physical form factors, and there are theoretically different SKUs for different temperature ranges, etc.
