In Ubuntu, pressing Ctrl+Alt+F1 brings you to a console login.When you press Ctrl+Alt+F3 it also brings you to a console login. My question is, why use Ctrl+Alt+F1 over Ctrl+Alt+F3 or vice versa, and what are the differences? Why is Ctrl+Alt+F1 always mentioned but never Ctrl+Alt+F3? Thanks for answering my question (if you do)!

Besides the number there is no difference.
There are some examples where more than 1 tty is useful.
tail -f {logfile}
will show new entries that are added in the logfile. Where you can use another tty to start, stop a service or do some kind of command line instructions, or do something in mysql.same goes for analyzing CPU usages on your system: have
sar
ortop
/htop
run on 1 tty and then use another session to start a browser, a command or service and by switching tty you can check what happens.
And yes you can do that from a terminal in the desktop but not everyone has a desktop ;)
