The tmpfs.

Yes, but it can hold a file containing the filesystem data which is
unpacked into RAM during start-up. In fact this is common behaviour
with initrd unpacked to RAM during kernel initialisation and
mounted as /, after which the kernel can set up the partition it
wants to use as / and chroot to that. That second partition can be
an ext4 filesystem such as RPi OS uses, or it can be a tmpfs or
ramdisk with contents unpacked from an archive on the FAT FS into
RAM by the init script in the initrd. Or / can even just stay in
the initrd forever (which is what happens in most distros if the
latter steps fail).

So a Linux file system is really optional. The only FS you _need_
for booting on RPi or UEFI is FAT, because that's what the firmware
can load the Linux kernel from.
