You really should read some awk tutorial to get a grasp on how it works and what are the defaults.

awk 'expression'
is equivalent to
awk 'expression{print $0}'
which in turn means do print $0 when for the current line expression is true.

awk '{expression}'
is equivalent to
awk '1{expression}'
which in turn means do expression (this can have side effects or not) when for the current line 1 is true (that is for each and every line).
