After looking at the videos, the content isn't even necessarily yours, as you didn't film any of it, which could be in violation of copyright. Unless you're trying to claim some kind of journalistic approach but this is very weak considering you're not providing any actual journalistic activity. You're uploading videos from other people/sources, not really providing commentary, or anything inciteful that would make people want to subscribe. You're just posting random videos of things that have happened. The content is also all over the place, which I guess is okay considering the clips are on a variety of topics. There's no real incentive to subscribe IMO based on what is being displayed. I see it maybe being suggested on my feed, or FB, go to it, watch, and leave.
If you look at the videos with thousands of views and cross-reference with the release then they probably coincide with the event, like the lebanon explosion. The 122k watched video probably coincides with the event and the person involved whoever Harry Maguire is (I've no idea who he is, but I guess he's popular).
My point is, you'll get the views and time needed, but I see no way to get that 1k quick subs by just reposting other content, and if you do, well you gamed the system.
