I think they are surprised that there aren’t any other bespoke or legacy or somewhat exotic OSes being used for any of them. Or maybe BSD or something.
The hardware is generally more mundane on that front, and even the ‘exotic’ ones are most readily accommodated by Linux (almost all x86 based, with a handful of POWER, ARM, and one that is allegedly DEC Alpha derived).
Generally speaking, a Top500 is a bunch of x86 servers usually nowadays with some GPUs in them connected by ethernet or infiniband.
Long time now. Linux runs almost on every device, not just computers and phones.
