The missing label here is “per 100 grams.” That omission does a lot of work.
Example: 100g of chia has ~34g of fiber, but also ~486 calories. 100g of raspberries has ~6.5g of fiber and only ~52 calories. So per 100 calories, raspberries actually provide substantially more fiber.
And somehow the “best protein foods” list includes tofu at 17g/100g but skips things like tempeh (~20g) and seitan (~25g).
