I would say that there definitely is a skill gap between greenbeards and greybeards in the game. But the great thing about DRG is that you wont notice it so much on the lower hazard levels. I had around 150 hours headstart in DRG when i played with my teammates during covid and there was a noticable difference in skill level when doing hazard 3-4, but on hazard 2 everyone could follow along and it was somewhat of a challenge for me because low skill players dont kill aliens that efficiently and the amount of aliens scale with the amount of players you are.
