Initializing HUD text for clients

I am trying to get text to initialize when the player spawns, text for the fire rate and ammo. Currently the only text that updates is the server. The client that joins when I test with multiple clients remains the default text which is None and 0. I do not know much about the GameState and PlayerState classes and have been looking into using them. The game I am making is an FPS and multiplayer so will I need to use these classes in order to achieve this? How would I go about updating the text for clients when the game starts?
