Minecraft Storage

So I have a realm and I add some packs. It is telling me I need to download these packs but it says I don’t have storage. So o go clear a lot of storage. Now Minecraft is telling me I have no storage to join my realm and I can only play on my phone or sometimes computer. But my main device is nentendo switch. Photos are attached. And no the packs size is not bigger than the amount of storage left.
