You can not tell from that as he could be using a armv7 system and run a aarch64 kernel, The foundation always run the 64 bit kernel on the 32 bit system. The 32 bit installation script sets the flag in the config.txt file to run a 64 bit kernel on the 32 bit system on the rpi4.
From /boot/config.txt # Run in 64-bit mode arm_64bit=1
