It's not because a dairy cow HAS to be thin, its because she has been genetically selected to put most of her energy into producing milk instead of in the rest of her body like beef cows.
That all depends on her breed and her body type. If she typically looks thin and sports a large udder between her legs, then it's likely that she is a dairy cow. If she is more blockier, not quite as thin and sports a smaller udder, then she would be a beef cow.

Holstein cows are a breed of dairy cattle known for their large size, distinctive black and white markings, and high milk production. They are valued for their ability to produce large quantities of milk with high butterfat content. Holsteins are a popular choice for dairy farming due to their efficiency in converting feed into milk.
