That sounds like a 32 bit OS on 64 bit hardware. Not sure if uname -m is the kernel or the hardware, but perhaps you're running a 32 bit userland on a 64 bit kernel? Seems that Pi OS switched to a 64 bit kernel on the Pi4 in March 2023: https://github.com/raspberrypi/firmware/issues/1795 It looks like 'getconf' returns glibc parameters, which would be 32 bit on a 32 bit userland.
