All right; as I've already said, I am trying to help. First, I will post what I see when I try to view the video you embedded in your post.
You can see it because it is
your own video. Now, I will get the setting you need to change from my own Creator Studio. I sincerely hope you haven't gone to YouTube Studio as the setting area is different, and I don't know it myself. The first thing you need to do is go to your Video Manager. Look to the immediate right of the video you wish to edit; there will be a button called Edit. Click that and you will see the following controls below a playable version of your video. Click the one I've circled.
Now, you will see the screen below. I've set this video to match the setting on yours which prevents others from playing it. You will want to check the unchecked box.
As this is obviously going to take more discussion than I thought, please allow me to make a small suggestion?
Please at least learn to properly USE YouTube as a creator before you start worrying about monetization! It would seem that you don't even know the upload set-up controls as well as you should in order to manage a channel.
I'll answer more of your reply when you've dealt with the embedded video problem. I'll check back after lunch to see if you've done it.
