Important: I used to have the KDE Plasma DE installed but I removed that months ago.
I checked activity monitor like I do a lot, and I decided to check the "all processes" button instead of just the "my processes." Now I see a lot of KDE-related processes like things starting with kworker, and other things that start with "k," which is what most KDE things start with. (I also see lots of other processes like loop32 but those have nothing to do with this question.)
First, are these KDE processes that I don't need? Secondly, if they are, how do I get rid of them? There are so many processes that start with "kworker" and just overall the letter "k."
Here is a list of some of the things I'm seeing: kworker*, kblockd, ksoftrqd*, kthreadd, krcommd, kintegrityd, kswapd0. These are not all of them, this is just a sample.
Also, here's a picture of what I'm seeing as well (picture mainly focused on kworker):
First, are these KDE processes that I don't need, and are from KDE Plasma? What are these processes? Secondly, if they are what I think they are, how do I get rid of them? There are so many processes that start with "kworker" and just overall the letter "k." The only app I can think of that is developed by KDE that I've installed is Kdenlive, but that's an AppImage.

kworkerfor one means kernel worker and relates to threads on your system, and not KDE. Don't forget K from Kernel and K from KDE share the same letter (ie. if you want to complain about KDE processes you should be ignoring kernel processes which relate to the Linux Kernel; and I've yet to recognize a single KDE thread in your post) – guiverc Mar 10 '22 at 21:13
