I am very new and accidentally loaded funds into a sample wallet on the Bitcoin.org information site instead of my personal wallet.
This happened October 11, 2018.
Would you please help me.
Your coins are gone. Sorry.
As KappaDev found, the transaction was confirmed, so it cannot be reversed. The only way those coins can possibly be accessed now is by whoever generated that address, if they still have the private key. It could have been someone working on the web page at bitcoin.org, or it could have been someone from coinspace who provided the image. (I wasn't able to find any image on bitcoin.org with that address in it.)
However, you can see here that several other people sent coins to that address, as far back as 2016. None of them have ever been spent. So it's likely that whoever generated the address no longer has the private key, or never saved it in the first place, or at any rate has no intention of using it. And even if they did, you would have no way to force them to give the coins back to you.
