I'm relatively new to programming as a whole and some tutorials have been telling me to use ls -l to look at files in a directory and others have been saying ll. I know that ls is a short list, but is there a difference between the other two?

This is located in your .bashrc:
alias ll='ls -al'
By taking a look at the manual pages for the command ls, you can see what those two attributes accomplish together:
-a: do not ignore entries starting with..-l: use a long listing format.
So you can understand that ls -l would ignore any entry starting with .. That's their only difference.
EDIT:
Let me note, that, as commented, the ll alias differs from installation to installation. In case you are wondering what's yours, please open up a terminal and enter:
alias ll
This will show you how ll is set. You can then look up the additional attributes by typing:
man ls
ll is a common alias for ls -l. It is a part of the default .bashrc, with a couple more options:
$ grep 'alias ll' /etc/skel/.bashrc
alias ll='ls -alF'
