Let's break this down.
Professional skiers like Tom Wallisch, Torin Yater-Wallace, Rory Bushfield, Roz G, Kaya Turski, Devin Logan, etc., are making enough money to have the basic needs (i.e. food, water, a place to live) and they get free stuff from their sponsors (i.e. skis, boots, maybe bindings, clothes, outerwear, other apparel I don't feel like listing because this is taking me too long to type).
Also, they save some money for the future in order to survive with life's basic necessities in the future after retiring from being a professional skier, but everyone will remember them as legends like Travis Heed, Brogan, etc.
