Correct! Firsthand means that you are the first to give or receive the information. "Firsthand" can also be understood as "directly". In the example, you hear information directly from the original source. Ex: He gave a firsthand account of the battle. = He was directly involved in the battle and shared his experience with others. Ex: He's not a spectator and would rather participate so he can enjoy the action firsthand. = He doesn't want to watch the action. He wants to be directly involved in the action.
