Yep, I have received gems but not many, usually 9 or 10 in one go.

I saw the video you linked. Those weapons and armor are present in the game and available for all players. But due to the randomness of what cards you get you don't get to see most of them.

For extracting files from the game you will need a program which can read and manipulate Unity files (Shadow Fight 3 has a different way of storing files than Shadow Fight 2). There are some available online, many of them are free. It's a bit of a lengthy process though. If you can, wait for a bit. All the images will be eventually added to the Wiki :)
