You seem to know that $ and ^ anchor a match to the end or the beginning
of a string. So you should also know that in the absence of one of
these characters, the match may start anywhere in the string. So the
statement works fine as it is.
However, stylistically s/[0-9]*// is better written as s/[0-9]+//
because the case where no digits match is better classified as
"not a match".
