You don’t need a high level of technical skill. You can learn everything you need to get started in a few minutes of tutorials or walk throughs. The rest you learn as you go.

Bear in mind no every linux user has memorized every terminal command and the whole file structure. Lots of people are just casual users who learn what they need.

One of the things I wish someone had told me at the start of using linux is that initially your desktop environment will effect how you feel about linux more than the distribution or specific architecture of the OS.

The good news is they’re all free. Try a few things and see what you like. IMO Fedora is a great, beginner friendly Gnome or KDE experience. Mint has an excellent Cinnamon and XFCE desktop either of which will feel somewhat familiar to a windows user. Mint will also run on just about anything.

Also, it’s not binary. You can dual boot. If there’s something you need windows for you can use it. Over time you’ll eventually find that you don’t really need windows anymore.
