Will i receive creator royalties on this CNFT i created?

I’m proud to say that I created my very first NFT ever on the Cardano blockchain back several months ago. That being said, i have no idea if I will ever receive royalties on it upon resell as I created it the day smart contracts were released. I’m not sure the tech for this was in place just yet so i’m trying to determine if i need to burn this thing and recreate or if the smart contract is applied through a market place after the fact. Any help is much appreciated.

Thanks in advance!
