Did I just messed up?

What else is needed?

Well, I'm one for aesthetics and ease of navigation on sites I visit. May be that's why I found that site not appealing or could it be that it's beautiful but it's just me not seeing that because I'm viewing from an android phone? Yes, I'm conversant with the electrum wallet site and I've to agree with you that its too isn't that fine. Perhaps, it's a thing with such sites as you've mentioned. I think I will leave it at that now.

The name of the wallet is aleph zero and my browser downloaded the JSON file automatically, since the windows OS was still very new I just deleted the JSON file off my computer and write down the recovery seed instead.

If you did not want a digitally stored copy of your wallet, I hope you do not believe that by deleting it, it is gone forever.  In order for a file to be completely gone, you have to overwrite your entire hard disk, something some Linux distributions offer as an option upon install.  Maybe there are easier solutions to overwrite the free space on a Windows device that I am not aware of though.

Then if we are talking about Windows, browsers, Aleph Zero (never heard of this wallet by the way?) and Internet.  Just because your Windows OS is a new install does not make it safe.  Especially if your Windows copy is not legitimate, if your browser does not have random invasive add-ons, if you have not downloaded, opened and/or installed random things off the Internet, if Aleph Zero is a legitimate open source wallet and, last but not least, if the Internet connection you have is secure at all.

There are just so many things to consider when you are talking about digital safety and security.  If you want that JSON copy to be useless, create a new wallet in Electrum and write down that seed just on a piece of paper by your own hands.  No printers!

This kind of site is not designed to win beauty contest awards, but to provide visitors with the information they are looking for. This site has a simple, clean appearance with some useful and relevant information. Its design may be outdated, but I don't think it's important. The most important thing is the software.

The wallet seed is all you need to recover your wallet. So if you have written it down on a piece of paper and stored it in a safe place, deleting the JSON file is not a big problem, if this is what you are worried about.
I never heard of aleph zéro before to be honest but here is what I found on their support page which confirms what I said above (bold part):

At the very last step, choose the correct location to save your backup .JSON files. They're an additional method of wallet recovery in case you'd lost your mnemonic seed phrase.
