That clearly is not even close to true. There is ALGOL (or rather its

BLISS, used by DEC. And if you include embedded RTOS, there's FORTH.
Just a couple I can think of in 30 seconds.
Let's not forget HP's SPL used to write the HP 3000's MPE operating system,
on a machine that never had/needed an assembler.

Or Planck, used to write Norsk Data´s Sintran.
