If you have read/write access to a folder then it is also part of your Dropbox and so uses your quota. So yes, regardless of how big the other persons quota is if its a read/write folder you will need to upgrade to view it if you do not have enough space in your account.
If you just need read only access they can use shared links via https://help.dropbox.com/files-folders/view-only-access which will not use your quota.
Can't I just view the folders in his space?
