Difference is that it doesn't cost you anything to use Steam, Epic game store, or Origin. You buy the game, you have the game. You can install 5 game stores on your computer and that's it.
For movies or TV series you need to have a subscription. That is the thing that costs money, even if you don't use it. People don't want to have 3 or 4 subscriptions, so that is why they pirate.

This is not a problem I see happening for games.
