Globs are different from Regular Expressions, as (partially) explained in What is the difference between Regular Expressions and Globbing? There have been whole books written on regular expressions, but tl dr there are a bunch of different ways to encode pattern-matching expressions. This paragraph will not pertain specifically to your question, but if you've never read about this, it'll be good to see it. And the asterisk * is technically a wildcard standing for "any string of characters." What is a glob? But they are specially named ending in a forward slash so the operating system knows they are directories (or folders, in everyday-person-speak).
