The setting you are pointing to is the setting for the size of Azure files, not the whole storage account. Azure Files allows configuring for normal or large file shares, which is the difference between 5TB and 100TB, these are the only options, you cannot set anything inbetween, and this only applies to Azure Files, not Blobs or Tables.
Within Azure Files, you create File shares, and these can be created at whatever size you wish. Again this is for Azure Files only. Blob storage does not allow you to set limits.
