Try joining the 2 tables as below. I think the IN will do a FTS always.
Correct me if I'm wrong.

SELECT to_char(NVL(SUM(a.bet_amount),0))
FROM sb_bets a, customer b
WHERE a.processed_DATE >= add_months(TO_DATE('07011999 000000','MMDDYYYY
HH24MISS'),19-1)
AND a.processed_DATE < add_months(TO_DATE('07011999 000000','MMDDYYYY
HH24MISS'),19)
AND a.customer_id = b.customer_id
AND b.licensee_id = 6130;
