It has some protein, yes. Nutrition facts are essentially rounded, though: that's why you can have things with "0 calories." They still have calories, but if it's like .4 calories, they can say it has 0.

A serving of mayonnaise is very small since it's a condiment, so if it has like .3 grams of protein or whatever, they have to list it as 0.
