Someone already create www.directory.io
but I think this site is only prank

Its good that guy who make this site didnt
implement address search option
So is it his website real or just fake?
Do we have to worry about is?

Its real, but you dont have to worry about it. They dont have a database with all keys (there is not enough storage space on the planet for that), they just generate them on the fly.

The chance is extremely low, you better worry how to keep your paper wallet safe & secure.
If you worry about it, split your bitcoin to multiple addresses or using multi-signature address
So if two people have the same private key, they have the same wallet??

No, wallet is the software that handles the private keys for you.
So the website is useless?

Well you can use it to generate private keys if you want. Its also very informative with the right information and you can test yourself how likely it is to find a used private key.

Or for what do they use private keys than?

They dont store any private keys, thus they cant use them. Thats the "fake" part others are talking about. You go to a specific page e.g. 1 and have there listed the private keys from #0 to #19 because they show 20 (the actual number is probably different) keys per page. If you pick the 3rd key from the top of page 42 you have the private key that is representing the number 20*42+3 = 843. Private keys are just that, numbers. Your chance to find a used private key while browsing that page is very low. The keys on the first few pages are the exception because some people thought it was a smart idea to use the private key #1 or #8 or #13 or #17 or #42 or #666 or any other number humans tend to apply higher meaning to.
