"Who can access the additional and in-game content that is associated with the game?
Additional content of the account owner will be available to the guest only if he does not have the main game. The guest will not be able to purchase additional content for the main game that they do not own. Any player can purchase, trade, earn, or otherwise receive in-game content while playing, but in-game items cannot be shared between accounts. These items remain the property of the account (user) who purchased or received them, regardless of whether it is a guest account or the host of the main game." https://store.steampowered.com/promotion/familysharing
You could use Steam Family Sharing but it's not possible to play Competitive matches (maybe Extra counts too), article here :

I don't think this should be possible or it's true.
You probably bought dlc on Steam too. Can you check in Steam Library - Rocket League - Properties - DLCs tab ?
It's currently not possible to share Premium old DLCs across connected platforms without purchasing there.
It may be possible in future - maybe next few months or this year, nothing exact shared yet.
