I noticed that in a few tutorials and screenshots that I do not have all of the pre-installed macros. This is what I have (see screenshot). Am I missing any and if I am, how do I download them? Thanks! [40%20PM]

All of the default installed macros, and a bunch more, are in the Macro Library within Keyboard Maestro (Window ➤ Macro Library). There are then endless more you can download from the forum Macro Library: https://forum.keyboardmaestro.com/c/macro
