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.

The main difference has traditionally been the package manager and update schedule, though a distro might offer several options for the second one.
Relatively recently we got another differentiating feature with immutable distros, where updates don't happen with a package manager but often by downloading or building a complete new image with the newer versions.
Other than that distros mainly set the defaults for you, but you can always change that to work or look like another distro with enough effort.
Basically, don't worry about it and use what works for you
