[Harry Potter] How well do wizards need to aim their wands?

Does a spell just kinda find and hit the general person they are aiming at? Can it hit someone close by making it a risk to try to hit someone with a spell if they are by or holding someone you don't want to hit?

On the one hand, we never hear anything about marksmanship in the books. On the other hand, we know that spells can miss. Given that information I’d infer that rather than spells flying on an unerring line from the tip of the wand like a laser pointer they have some basic ability to adjust their trajectory similar to aim assist in a video game.
