quotes usage for column names when using AS keyword
What I learned from previous course regarding AS keyword, we need to use quotes of column names in multiple words but not single word. When I see the example this video taken it seems that columns, "Email" and "Phone" are wrapped by quotes even even thought they are each single word. Is it ok that I understand I can use quotes for column names when I use AS keyword without thinking those names are single or multi words?

The quotes are required when the names contain spaces or special characters. Otherwise they are optional and can be used or not as you choose.
