From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know where you got your information from, but your mental model on how and why things work the way they do in both linux and windows seems to be really off.
Since you seem someone that is actually interested in understanding this stuff, I strongly suggest to find some better sources as your base
When I was taking cyber security, Sandboxing and Linux was one of the topics which was brought up.

Not sure when I associated it with the entire OS. It appears that the Host OS can be sandboxed for added security, and some containerized applications like Flatpaks are sandboxed. But not all applications are. Like the OS provided packages in most package managers.
