Anecdotally my parents use linux because of me using it on my computers too and one nice thing about it is that they can have a consistent UI. The kind of changes that happen with at least some well established desktop environments and window managers are not nearly as radical as when Windows changes where things are at in their UI. There might be some UI tweaks here and there depending on your choice of desktop environments but I don't use rapidly changing DEs on their PC. With some of the simpler well established DEs it isn't typical that there will be a change so dramatic that you have to relearn how to use it like with Windows 8 or something. There are some such as GNOME that have undergone some heavy changes in the past but you can choose to use simpler ones like say LXDE or Cinnamon.
They mostly use the web browser anyway so it isn't like it was a really steep learning curve. Since they switched to linux the amount of help I have had to give them has decreased. If my parents did more advanced tasks they would need to learn some new ways of managing their computer yeah but for them they just browse the web, use Libreoffice and use the printer mostly. Even before they switched to linux I had them using a bunch of open source cross platform software for years before that which did help the process go smoother but Libreoffice for example has a similar UI to the classic Microsoft Word so it was not like it was a huge learning curve.
I do their software updates but me doing software updates has just been me typing "sudo apt-get update && sudo apt-get full-upgrade" and restarting. If there ever was a problem I would have to fix it but I would have to fix it if there was a problem with Windows too. I find linux to be easier to fix than Windows and the error messages to be easier to figure out. Overall the switch has gone well and there is less I have to worry about.
