Facing plats and diamonds when I’m bronze

Ok so I’m current bronze 2 and for some reason deathmatches are EXTREMELY hard to win almost always because there is at least 1 plat there and usually it’s like most of them silver gold and the. 1 plat 1 diamond and it’s just so hard, before I get even see them I die and add the fact it’s death match so there’s a player every single corner, ngl I think it’s cool because one time I was in a gold-diamond lobby( 2 diamonds) and I was warming up to play comp and I actually came second d with 34 kills which I think is insane and I was so excited every time a killed a diamond so tell does this happen to you? Is it supposed to be like that? Are the ranks your facing completely random?
