Is Apple One individual storage use separate from Icloud+ storage?

I currently have Icloud+ 200GB storage plan. I'm going to subscribe to Apple One individual plan, which has only 50 GB storage. I intend to keep both plans. iCloud + cost is only $3, & I don't want the additional features of the family plan or its added cost. How is storage use allocated between the 2? Do I have a total of 250 GB storage?

Thanks for any replies.
