HS Senior Trying to get into Cypto/nfts

Hi I’m an 18 year old senior in HS, I’ve been trying to do research and get my mind wrapped around NFT’s and the whole world of crypto, I’m going to be majoring in finance and I really want to get into the NFT/Crpto space but I’m not sure how to do that with very little to no money. I don’t even mean necessarily buy NFT’s, just how to get more engaged in the community and start understanding it more. Any advice?
