Is there any connection between gta online and story mode?

The verified evidence describes Grand Theft Auto V's single-player story mode, which follows three protagonists—Michael De Santa, Franklin Clinton, and Trevor Philips—as they attempt heists in the fictional state of San Andreas. The excerpt focuses exclusively on the narrative, characters, and open-world exploration of the single-player experience. There is no information provided about GTA Online, its features, or how it might relate to the story mode. Without explicit evidence linking the two, any claim about their connection would be speculative. The question may require additional sources that specifically address the relationship between GTA Online and the story mode to provide a definitive answer.
