Is there a greater answer for naming D-Block elements the way they do?

Ok so I’m going into my second year of college and I’m starting to learn more advanced chemistry (pray for me) I’m currently on the topic of D-Block elements and I was already aware of electron configurations and how to write them out… however what I have never come across prior was the use of another elements electron configuration to almost ‘shorten’ writing out one for example the electron configuration of manganese is [Ar]4s2 3d5 (embarrassing if I wrote it wrong but please correct me if I did) I had a general question, is there a deeper meaning behind using another electron configuration in a configuration or is it just chemists taking a shorter route and almost being lazy lol any experienced chemist please respond, I’m a baby chemist trying to learn!! Thank you a million.

In a way - both. Yes, it is "just" a short notation, but it also reflects on the fact non-valence electron configurations are quite stable and identical in every "higher" element.
