Are range variables kind of like the equivalent of alias in a SQL Statement?
Like for example:
Select Age,Name,Address, PhoneNumber
from Customer C and Invoices I

It seems to me that this is a likely comparison.

Not really. Aliasing takes place in the Select method / slect part of the query. Range variables do more, as they are also used to determine what you can select (myCustomer.Invoices) and how you want to filter (where myCustomer.Invoices.Any()).

Hope this helps,
