Well it's more that "fruit" and "vegetable" aren't really separate things. All edible fruits are also vegetables. Vegetable is just any part of plants edible to humans. There's absolutely no such thing as a botanical vegetable.

It's only that there is a botanical term for fruit (the seed-bearing reproductive part from the ovary of a flowering plant) and a culinary term for fruit (a sweet plant used in desserts and other sweet foods).

A strawberry is not a botanical fruit, but considered a culinary fruit. Rhubarb is generally considered a culinary fruit, though it isn't a botanical fruit either.

Then you have botanical fruits that are poisonous to humans, and are not vegetables either.
