The A300s pre-date the A330s by several years.
Qatar Airways first introduced the A300 in 1997 to allow retirement of the B747-100s that had been used on European flights. Not only were the 747s too big for Qatar at the time, they were getting expensive to maintain...
The first A330 was not delivered to Qatar until 2002, I expect in the late 1990s that the A300-600R was probably the most cost-effective type for Qarar - at the time they were still only a small airline.
Qatar Airways are in the process of retiring 2 A300s from passenger service and converting them to freighters, I would expect the rest of the passenger A300 fleet to follow eventually.
