Actually, no. The game says there’s a 50% chance that shots will land within the yellow circle. Which means that all or none could land within it. Just like there’s a 50% chance a coin flip will be heads or tails, but you could flip it 10 times and you’d be unlikely to ever get 5 heads and 5 tails.
The spread within the cone works on a bell-curve with highly inaccurate shots being as unlike as highly accurate shots (meaning that most rounds will tend to fall somewhere close to halfway between the red circle and the bullseye).
