So I followed what this video above told me to do, and I didn't get anywhere near the same results. So I opened up a new project in FL, simple pad, single snare sample, followed what it told me to do word by word. Here is an example of what I ended up getting:

And what I did:

So yes, I have no idea what I'm doing wrong, and would like to know so that I can sidechain my drums in my wip so that they stick out more. Also, on my WIP, when I tried sidechaining, the snare sample would change when I tried to sidechain it. Not as in it changed because there were less frequencies muddy-ing it up when I played the track, but the sample alone would sound different (had a more airy feel). I also have samples of the snare before and after attempting sidechain with my current wip.
Also, sorry for the picture being a bit big, didn't really feel like resizing
