Cryptocurrencies aren't really "Web3" though are they. Web3 is all the absolute rot that people have tried to glue onto a blockchain just so they can tick a buzzword box. NFTs are still a scam, even in Argentina.
There is no super formal definition of these terms, people think on different things when they hear about them. Even cryptocurrencies could not be crypto.
I will not start arguing about NFTs, it is enough to say that the technology is useful in one place and not in another and help people to transact internationally.
You comment basically proves the point of this thread! Everyone lives in their own echo chamber.
