Am I tripping or what?

So, me and my friend have just won a Head2Head game with a random guy. We duo queued and got a third random. The enemy was at least 2 premades one of them was diamond, and the third guy was this ruby player.

They actually played horribly and got their ass handed to them. And it's not like they were trolling. They were using all the mechanics and loadouts you could see in the major. SA1216 winch combo and dome shield.

Am I supposed to believe there's legit people out there with level 1 steam accounts in high rank elo being so tryhard, supposedly ruby and still be this bad?

Last time I saw actual rubies, they were dominating the whole lobby, like soloing at least 1 team completely. These guys played like sh\*t. And it's not even like this guy was new or something. Ruby since season 6. Crazy...
