Linux gives you REAL control of your hardware, for example I use it to directly control pins on the Board of various single board computers, You can do this also on big Motherboards to run specialised or even homemade hardware. If I have trouble with a USB device i can talk to it directly to find out where the problem lies. that is possible but very cumbersome on windows or mac. You can also run linux on almost any hardware you can get my hands on, and if you want to go really high end (i don't mean current gen gaming, but Cluster computers and distributed cloud computing on your own network) you can even make your own beowulf cluster with linux to offload workloads like rendering a video to dedicated machines within your cluster while your age gaming on the main rig.
Linux is also great for doing creative work, you find suitable programs for almost anything. I run a little videoproduction company/hardware development thingy 99% on open source linux software that is available for debian/ubuntu.
The OS is truly open so you can even make your own custom os that perfectly suits your needs.
Here are some projects i did that use Linux as the operating system and do stuff you can't do with windows:
Giant Resin based 3d printer:
Worlds first MacPro that does grate cheese:
a rig for moving timelapses/hyperlapses, moving cmara shots and stop motion animation (yes liek the expensive edelkrone stuff)
Digitizing an old Super 8 camera (a task some people threw a lot of money at before)
a pocket touchscreen computer( unlike a smartphone it allows you to run desktop software)
A VR system to play the original DOOM in VR
