PlayerStatusHealthValue is the actual value of your health, it's also inside HudPlayerHealth.res. If you want to move the health a little bit, move PlayerStatusHealthValue. If you want to move it a lot, then move the whole HudPlayerHealth part that you pasted above.
Make sure that you are moving both xpos and xpos_minmode.
Ammo is moved in hudlayout.res, it's called HudWeaponAmmo, move it as you see fit.
