I have used awk several times in different ways. I still don't find it easy to remember a command with as many punctuation characters as letters, like your first one. And I'm not even sure what the second one is trying to do. Print the user name, followed by the number of fields separated by colons? What good is that? Perhaps you've forgotten that not everyone can read awk syntax right off the page.
