Q: Victim of lucky winner

GO to Settings>Safari>Clear History and website data. Close Safari by double tapping the home button and then swipe up on and off the screen the Safari thumbnail preview. Tap the home button. Restart your device by holding down on the sleep and home buttons at the same time until the Apple logo appears on the screen.

You are fine, but going through these steps will clear Safari completely.

You have nothing to worry about. You didn't buy anything, give any confidential information away or click on any links.

Demo already explained what was going on. All I want to say is that you are indeed the "lucky winner" as you did not enter any data at all. Cheers and enjoy your phone....

This happened on my wife's iPad today. Glad to have this post
