The last one is the only "functional" cheat that resembles an aimbot. It is essentially an auto-clicker linked to your mouse movement. It fires your guns the microsecond your reticle touches the grey lead indicator.

An aimbot is a type of cheating software that, when installed and activated, automatically aims a player's weapon at an opponent. This process usually involves intercepting game data to identify the position of both the player's and the opponent's aircraft, then adjusting the player's aim to directly target the opponent.

Spend time in training rooms to understand the aiming lead required for different gun types and speeds.
