Created my first NFTs, could use some advice

Made my first NFTs at
Wondering if I’m likely to make any profit just making such random NFTs (I’m thinking, probably unlikely). Anybody know where I might find a guide on how to actually make any profit? Found lots of “how to create” and “how to sell” guides, but I really haven’t found any information on how to actually profit. Anybody willing to share their experiences and/or advice with NFTs?
