Matchmaking; Unbalanced and arbitrary

Hello Apex Enjoyers, 

I have once again started playing ApexLegends after a couple of years.
New Legends -and QoL, but the familiar maps and feel that I remembered.

In that 'feel' also hides a very negative and demotivating factor: the matchmaking system.
Whether it's unranked or ranked, the problem remains the same: I get put up against players who are way better than I am, while I (and the rest of my team) have to struggle with the mechanical skill and in-game coordination that is clearly several leagues below the opponents'. 
Furthermore, the 'skill-indication' at the beginning of unranked games also keeps me in the top 1% (I checked by solo-queueing for a couple of games), while my k/d this season/split is worse then it's ever been. I understand that k/d is not the greatest measurement of 'skill' but its the only thing we have in the UI.

I would love an explanation (-that isn't given in the first 20 google search results, I have done my research) because I haven't found one and can't think of any.

Kind Regards,
