I have yet to work with a $corp that uses Linux for workstations.
Overwhelming majority uses Windows. Some use macOS.
The ocasional developer that uses linux will usually be in a VM, or if IT policies allow, WSL.
So yeah, running cloud services doesnt require sysadmin skills, unless you assume copy pasting from oficial documention "sysadmin skills".
It boils down to what kind of jobs you look for.

If that's the extent of how you're managing your cloud setup, then I could equally argue running bare metal servers doesn't require sysadmin skills either. When I did contracting, a large part of my income was to come in and clean up after people had relied on "copy pasting from official documentation" as a substitute for actual ops.
At some point we hope to get to the scale where it makes sense to pay a human to do that, but at this point the additional cost incurred by an ECS instance over an equivalent server is negligible.
