Good luck! The way I see it: Linux has its issues, but so do Windows and Mac OS (and others). The cool thing with Linux though is that for many problems you can create/find some form of error logs, google them, and someone online will help you. In most cases they have solved that problem already.
Windows problems often feel like black magic: Something doesn’t work, but all you can do is knock on your laptop, turn it off and on again, and pray. Unless you’re lucky and find a shady program online that you can download and install, hoping the programmers mean well.
With Mac OS, you can often solve problems by throwing money at them. But sometimes that doesn’t work and then you can’t do anything about them and just have to accept the one way to use your computer correctly.
So in that sense I don’t think Linux is “harder”. There are problems of course, but you learn to think differently about them and are often able to solve them.
