It's both.  It has two Cortex-M33 ARM cores and two Hazard3 RISC-V cores. 
Only two can be active at one time, but I've read it can be one ARM and 
one RISC-V. No idea how you would pull that off.

I've got a couple of Pico 2 Ws but haven't done anything with RISC-V. 
There is a MicroPython uf2 for RISC-V, but that obscures the processor. I 
don't know if there are limitations between the two.

https://micropython.org/download/RPI_PICO2/

I think the C SDK is a similar situation with the build being controlled 
by CMakeLists.txt, the same as Pico and Pico 2 builds are differentiated. 

I don't know why they did it other than to prove they could. People who 
have bench marked it concluded the RISC-V core is slower than the ARM 
although possibly a little faster than the Pico ARM Cortex-M0+.
