Yes, as K mentioned - many of the stats (e.g. disk_reads) aren't updated until the end of the call. For more up-to-date stats, you can monitor v$sesstat for the sid that is currently executing the sql, e.g. select sid from v$session where sql_hash_value = <hash_value for query you're interested in>; Then select the stats of interest from v$sesstat for the sid(s) returned from the above query.
