It looks like a Pico clone with some added features. The pinout looks to be the same so ADC pins should be in the same place and work the same.The board shown in your most recent image is NOT a Raspberry Pi Pico board.
I'm not sure about the pinout being the same.
Compare with https://pico.pinout.xyz/
It might just be dodgy (unreliable) silkscreening, but there seem to be some differences in the (critical?) 'ADC' area between Physical Pins #31 and #37.
