Professional surfing is not physically demanding and doesn't require needs different from normal people? Do you think that they just casually go out on the water once a week? Also, from my brief experiences surfing, I seem to recall it being one of the most physically taxing sports I've ever done, in terms of total body usage.
Valid points about needing to distinguish between professional athletes who were vegan at their peak versus after their peak, and diving into the details about how precisely how "vegan" each of the people I quoted actually are.
