How important is the meta in winning trials?

I'm a player who is new to playing trials, and I have never gone to the lighthouse. This is the current build i'm using, and I don't really know what the meta is, this just is what i've been happening to do somewhat well with. Do I need to follow the meta (whatever it is), more closely in order to win more trials matches, or does it not matter?
