Replying to Pro skiing career much shorter than pro snowboard career

i noticed that pros like tanner who is like 24 now i think and this is his last season competing just kind of average ending their real careers in their early-mid twenties where snowboard pros stay going until late 20s and even early 30s. mikey leblanc is 33 and still does comps and video parts and shreds urban, and jussi oksanen and heikki sorsa are 29 and absolutely shred, like totally on top of their game for at least a couple more seasons. am i just overlooking a lot of pro skiers or is this the case? i dont think injuries are really a factor because it seems like they both get injured the same frequency.
