From one of my friends' experience, yes in most cases you will get the lowest quality possible skin but it doesn't mean you can not get better qualities. I think it really depends on what kind of skins they have in stock.
you can also find some screenshots that prove users get some good quality skins from Gamehag. (Discord server - Proof submission)

My previous thread was deleted, so here I come again. Somebody who knows what quality you get if you order a skin? The site says 'random quality", should I expect the worst?
