Google Ads keyword score is 1-3/10 in competitive niche, but ad relevance is Above Average or Average for 5 out of 7 keywords

I know Quality Score is unimportant to semi-important in certain industries and niches, but I’m in a really competitive industry with really expensive keywords and our ads are doing “alright” but I want them to be doing a lot better.

Our ad relevance is average to above average for every keyword, but our landing page experience and Exp. CTR are below average for every keyword. Are Landing Page Experience and Exp. CTR more important to quality score than ad relevance? I’ve done about everything I can for the campaign (and I’m going to keep making improvements as I can), but it feels like Landing Page Experience and EXP CTR are killing me.

I know ad relevance is on me and landing page experience is on the organic side, but who is more responsible for Expected CTR? Or is Expected CTR a 50/50 split?
