If all my photos and video are stored to iCloud, if I delete some off my iPhone will the deleted items still stay backed up to iCloud forever?

I Don't have access to a PC and won't be able to buy an Apple laptop (that I dearly want) for another month or so.

i Desperately need to know if the photos I recently deleted off my iPhone will still stay stored in iCloud backup till I get the laptop and and be able to manage my storage better. Photos are of my kids and I absolutely cannot chance loosing them.

im worried Icloud will see that I've deleted off my iPhone and also delete from my icloud backup?

help pls, I have 13 days left in 'recently deleted' items and want to know if they will stay 'somewhere in the cloud' and they are safely stored there.
