K/D ratio has to be one of the least important stats in Apex.
If you play ranked, your K/D ratio will go lower. If you want to just raise your K/D, play public matches. That's all there is to say about whether it matters or not.
If you are super good at the game, like Diamond or above, your K/D ratio might matter, but also probably not, considering your rank matters far more.
