Beatmap Nominator and Loved Captain here, I can give my perspective on both accounts:
Ideally, in the aim for Ranked the best thing you can do is to keep mapping. You don't improve solely from feedback though it is crucial so I admire you reaching out to circles. Though being dismissive about people trying to help isn't the way to go, I used to have your mindset, but the truth is, deleting your maps restarts all progress you had, having the maps open and readily available increase their reach and can help others with their goal to help you.
If you have dreams of being a mapper, my advice to you, is to keep going. You've had an account for 2 months, you won't be a genius right away! I strongly believe that feedback that simply tells you "it's not ready for Ranked" won't get you anywhere so I encourage you to instead seek feedback about how to improve your map bit by bit, as you keep improving the quality will shock you.
Take time to listen to those who are giving up their time to give you the help and you will see insane progress, try to expand your own mindset, rather than limit yourself based on what little you currently know. There are mentorship cycles happening on a seasonly basis, I recommend looking to join in for the Fall cycle, you will learn a lot! Go in with a positive outlook, I believe you can make great things.
Loved is a different story, Loved aims to promote creativity without recognition, those maps the community truly enjoys and wants to see thrown into the spotlight. This is why aiming for Loved status is discouraged. It shouldn't be a goal, do you want to map a fun gimmick? Go ahead! Map it because it's fun to make or play, not because you seek to gain a benefit from it. Games should be fun, so make them enjoyable, that's a good thing to stand by.
If you need any insight or advice my DMs are open, let me know! Hopefully I gave you some good insight though.
