How does character progression work in gta online?

The Wikipedia entry for Grand Theft Auto Online describes the game as an online multiplayer action‑adventure developed by Rockstar North and published by Rockstar Games. It notes that the game is the online component of Grand Theft Auto V, set in the fictional state of San Andreas, and allows up to 30 players to explore an open‑world environment. The article mentions that players control a customizable silent protagonist but does not elaborate on how character progression, such as experience points, levels, or skill development, is handled in the game. Therefore, based solely on the verified evidence, we cannot provide details about character progression mechanics.
