It would be interesting to actually ask a group a people this question. I'm pretty sure a lot of people would fail.
It feels like one of those puzzles which people often fail. E.g: 'Ten crows are sitting on a power line. You shoot one. How many crows are left to shoot?' People often think it's a subtraction problem and don't consider that animals flee after gunshots. (BTW, ChatGPT also answers 9.)
You assumed gunshots. He could have used a bow and arrow, or a blowpipe.
