I want to win the lottery.
Sometime you don't get what you want.

Consider running DBMS_STATS against the table.

The lack of planning on your part, does NOT constitute an emergency for me.

How do you get rows counts without actually counting the rows?
Either you count then rows or DBMS_STATS count the rows.
pick your poison.
