DLC and bug fixes are downloaded as patches, once online support is gone you won’t be able to download that stuff again. So if you buy a second hand cart after online is gone or you uninstall the game data after online is gone there’s no getting that back. It’s gone without a modded console.
For example:
Breath of the Wild is on version 1.3.1, all changes since the version on the cart you have will be impossible to get once online functionality is gone.
I’m talking about when Nintendo no longer support the online functionality of the console
And in the regards of patches
You will be unable to get patches for the game after they drop online support
