Do gta online characters differ from story mode characters?

The single source cited is a Wikipedia article that describes Grand Theft Auto Online as an online multiplayer component of Grand Theft Auto V. It explains the game's release dates, platform availability, and open‑world setting in San Andreas, but it does not mention the story mode, its characters, or any comparison between the two modes. Because the information is limited to the online mode only, it cannot be used to determine whether the characters in GTA Online are different from those in the story mode.
