In any given game, if i have my local player position (x1, y1, z1) and angles (h, v), and I know a given position (x2, y2, z2), what is the formula to update my angle to face it accordingly?

I know of getting the euclidean distance, what are the other formulas that people typically use to make an aimbot?

I do not need 100% accuracy, so long as it is mostly accurate that is all I care about, thanks

There's no good/simple way of answering that question. How do the angles correspond to the 3 axes- at the very least, which way is positive / negative? How are they encoded- radians, degrees, normalized (-1.0 - 1.0)...? Euler angles can be more complicated than they seem (e.g. extrinsic vs intrinsic), not to mention the possibility of dealing with quaternions...
You probably aren't going to get anyone to walk you through this.

Look up educational material on high school level geometry / trigonometry to get started.

This website was decent when I was in high school a while ago:

Maybe look into basic 3d game development too. Specifically coordinate systems and representations of rotations. There's plenty of videos on youtube.
