You have only one user call reported as there is only one user call executed
directly via oracle program interface (OPI).
However you would have one thousand recursive calls executed as well, these
are database calls executed via recursive program interface (RPI). These
calls are shown as "recursive calls" in v$sesstat.
So, total number of DB calls = user calls + recursive calls.
