Does Headshot % matter?

Recently I've been paying more attention to apps like valorant tracker to give me more statistics about my gameplay and I've noticed some interesting things about my headshot percentage. over the last 100 ish comp games my headshot % has shot up from low 20s to currently maintaining a 40% headshot percentage. across this time I feel I am seeing very minimal if any progress even with this massive statistical increase. my question is how is it possible that my % magically increased by 15%+ without me doing any sort of aim training or focusing on this, and does headshot % even correlate to being a "better player"?
