Anadius updater help?

Fair warning : I know it might have been answered already but i'm autistic and struggle to find my answers in other people's questions.

Alright so, I know the unlocker still works since I still have my DLC's in my sims 4 game but what will happen when the game updates? Will my packs still work? Do I need to find the packs manually and download them again even if i have them already due to anadius? If I have another thing like Fitgirl, what will happen with my Anadius things? Is there another sort of updater somewhere?

I'm not really good in computer stuff but i'm open to learn if someone is patient enough to explain it to me 😅
