I think you are right. Vegetable has only a culinary definition, not a botanical one. And I don't think many people would classify watermelons as a vegetable, except that watermelon skins are sometimes used for cooking.

On the other hand, watermelons are definitely fruits, in both the botanical and culinary sense.

This is reminds me of this video: [No Such Thing As A Fish](https://www.youtube.com/watch?v=uhwcEvMJz1Y)

You can grill watermelons, mix them with sheep cheese etc. Watermelons are so much more than just a sweet snack if that's what you mean by fruits in the culinary sense.
