I find it annoying and am asking if it works.

Yes, because Custap Berry utilizes Priority and not the Speed stat.Priority will make sure you move first, no matter what. However, if your opponent uses a move of higher priority, they will move first.
A Custap Berry allows the holder to move first in itspriority bracketwhen HP is below ¼. If the holder has Gluttony, then it eats its Custap Berry when its HP drops to ½ or below.
Move priority is not affected by Trick Room, which only reverses the Speed-resolved order of moves within a priority bracket; moves with higher priority are still performed before ones with lower priority. Some held items and Abilities also affect a move’s resolution within its priority bracket (ignoring Trick Room), but not the priority itself.
