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.

Can someone ELI3?
(I'll attempt this based on my understanding of both)
Pouring a cup of juice is something an adult needs to be involved with.
sudo is when you ask for permission to pour your own cup of juice. You ask an adult, they give you the cup and the juice, and then you're responsible for pouring it. If the adult isn't paying attention they may leave the fridge open for you to go back for more juice or another beverage, but otherwise you're limited to the amount of juice the adult has given you.
run0 is when the adult just gets you a cup of juice. You tell them what you want, they go and pour the juice, and just give you the cup with the juice in it. You never enter the kitchen, so you don't have access to the fridge, just your cup of juice.
This is an extremely good explanation.
Okay now please ELI1

when in need, cry out for mommy!
caseyweederman is not in the sudoers file. This incident will be reported.
Some executables are special. When you run them, they automagically run as root instead! But if sudo isn't very, very careful, you can trick it into letting you run things as root that you shouldn't be able to.
Run0 DM's systemd asking it to go fork a process as root for you, and serves as the middleman between you and the other process.
You had me rolling, bud.
