But brother, headshots won't just start landing automatically just by changing the sensitivity. You will need to practice daily and adjust the sensitivity a little bit according to your own style.

If you mainly focus on Booyah then I'll suggest you these points:

Fix Your Landing Spot : Mars Electric, Rim Nam Village, or the outer ridges of Peak and avoid blue zone.

Avoid fights in open fields or away from the zone edge. If you hear gunfire, do not blindly rush to third-party unless you have a clear, protected angle.
If you can do any third party that will be best to secure kill.
Edge-of-Zone Rotation: Instead of rushing to the dead center of the safe zone, you go though short edge of the blue zone.
Always prioritize hills, roofs, or towers. Shooting downward gives you easier headshots and also never leave a cover without a plan.

Weapon I'll suggest: M4A1 or SCAR paired with an M1887 or MAG-7.

Character skill: active- Alok or K
Passive - kelly, moco, hayato

To survive with random you can do:

Don't try to lead. Follow the majority of the team, even if they make a bad call, If a random teammate blindly rushes a house and gets knocked, do not instantly rush in to revive them in the open. Instead, wait for the enemy to push out to finish your teammate,
