The shot MISSED completely,
because the game has both pseudo-realistic BULLET PHYSICS,
and the good oldschool CONE OF FIRE.

The BULLETS themselves are actually tiny, with all NPCs (and player) having very precise hit detection, meaning you can indeed miss by a single millimeter.

...Or to put it into zoomer-friendly way:

Guns are NEVER laser accurate in STALKER, not even when you ADS, and you MUST learn each weapon's + AMMO TYPE'S behavior in order to get the most out of them.

Also, (You) have never handled a real firearm before, buster.
