"You have been hacked" message on Safari, is it real?

So just now I was on safari and then I pressed the two squares that are connecting at the bottom right of my screen to exit out of the thing I’ve searched, and see this message from “Apple” so I clicked it and it put a two minute timer and said “you have been hacked, if you don’t download this app and connect VPN to your device all your photos and browsing history will be sent to all your contacts. The hackers will also get all your personal information and steal your identity” I don’t know if this is true or not so me being scared I downloaded the app and paid the subscription. Is it worth it? Or is this the hackers making me download and app and get my information like others have been saying….
