pg_stat_statements only collects cumulative runtime.  The OP seems
to be asking for the runtime of each execution of each statement.
The only way to get that is by logging the durations (see log_duration
and related settings) and then scraping the postmaster log.  You
might want to use pgbadger or a similar tool to help with the scraping
and subsequent data analysis.
