I started using Linux because I was curious. I installed the "Ubuntu distribution" (a Linux "flavor" with preinstalled software to make your life easier), and started goofing around: first navigating the web using the web browser, which isn't a much difference experience than windows, then did my programming courses in there for university, installed a few games, and broke the system many, many times because I had no idea how to install stuff ! (Protip: it uses a "store-like" approach, like on Android, rather than running .exe installers ;))

The best way to learn it, is to try it ! I'd suggest Ubuntu, because it worked for me 15 years ago, and it's the simplest approach you have to discover it, as the system will be ready to do the most basic tasks (browse the web, edit document, watch videos, etc...). You won't have to struggle with searching and installing software, and can just discover it.

Now about your question, it's not about how Linux is "better" than windows. It isn't, and doesn't try to be. The most important trait is that it's "different", and you gotta find what it means for you.

I won't lie, using Linux as a daily driver is harder than using windows (much less than it was 15 years ago!), because of hardware/software compatibility, user support, etc... But it is also so much refreshing! You get to change every tiny bit of your system, you can swap components easily, eg replace the default web browser, change the windowing system for another "desktop environment", and take back control of your privacy while doing computer stuff.

So here's my best advice to you: Try it out! Break stuff, restart from scratch, and keep learning that way. This was the most fun I had regarding computers for my whole life, and now I simply cannot switch back :)
