Of course SCCM was SMS. More recently they dropped the “Endpoint”
Only because they wanted to re-brand Intune as Endpoint..
(I remember SMS - when I was doing y2k stuff we used it to push out patches.. Ah the fun we had as suceeding patches either changed the date display rules or broke previous patches. I was mostly doing Unix & firewall patching  but still go involved on the Windows side when the poor little dears  needed someone with actual technical skills  to help..)
 Out of the 40 or so people on that contract, I was the only one that had used anything vaguely unix-like - I'd been using linux for about 5 years by that point. And I'd managed a firewall at my first techie job (put in a 64k leased like with a Sun box running Firewall-1) so was the most qualified person in the team.
 Let's leave it at the fact that most of them were barely-qualified MCSE types and, if they came across anything not covered by their courses, lacked the ability or experience to actually do anything.
 By that point I'd herded DOS, Windows 3+, OS/2 (all flavours), a bit of S/370 herding, Windows NT Server, OS/2 LAN Server, linux (at home).. So I was quite used to OS-context switching (like I am now - my main machine is a Mac but I have work-build Windows VMs for when I need to manage Windows stuff (like SCCM) that isn't done via a web point-n-drool.
