Why would a bass bite an artificial bait with this many bait fish in the lake?

I asked myself this question this morning. There were 5 that bit a DT-6 , a DT-10, or a worm. Not much else. The lake was full of boats but I didn’t see any of them doing any good. Lots of moving around. Must be a tournament tomorrow. Fished both ends of the lake but there was no secret spot.
