Everything in awk has the form condition{action}. If the condition evaluates to 1 then the action is performed. If the condition is omitted then the default condition is 1, so the action is always performed. If the action is omitted then the default action is performed, which is {print $0} . In this case the condition is "1" so that evaluates to 1 and the action is omitted, therefore {print $0} is performed, which is "print the entire record".
