How do people learn certain languages "just" through video games/music?

Just a discussion and something im curious about. Let me know your opinions too, i'd love to hear it.

Many times im on this sub i've realised that lots of people learnt English through playing video games or listening to music and according to those comments thats what they ONLY used BUT would that apply to other languages too?

I know english is literally everywhere & needed everywhere in the world so its very easy to get content & interact with it but also i've seen people say that english isnt an easy language to learn. And many people in many countries of the world still dont know how to speak english (i have family members that just speak arabic and the only english words they know are the basics of the basics like "yes" , "no" , "hello" , etc)

Lets take romance languages as an example, which use "English" letters/alphabets so as person who speaks English you're already familiar with the writing system (i know there are other languages that use the same writing system but im talking about this language family specifically just as an example) but I dont think I've heard of anyone learning a romance language using ONLY video games/listening to music (correct me if im wrong) without studying a bit of grammar on the side.

There are big communities online of romance languages & i'd believe there is also lots of content to interact with to learn but how is English learnt only by listening to music/playing video games while other languages require extra materials to learn?
