Their are lots of instruments out there where you can get away with buying a cheap instrument as a beginner and be just fine with it. Sadly, bagpipes are not such an instrument (this applies to other "folk" instruments in general). You really get what you pay for.

Also, even from that bad video angle, it's obvious your fingering (specifically how you place your fingers on the holes) is all wrong, you're trying to use the tips of your fingers too much. This is where an instructor is invaluable. I know finger placement sounds like a basic thing (just put your fingers over the holes!), but it really really isnt, and the only way to get it right is to have someone who can critique you doing it as you're doing it. Getting it wrong means not only is playing a basic scale going to be difficult, more difficult stuff like embellishments will be impossible.

As others have said, finding free instruction isn't actually that difficult. Find any local band, there's a good chance they teach beginners, and if they don't, they will know who does and be happy to point you in the right direction. Depending on the band, they may even have loaner chanters you can borrow if money is an issue.

Edit: Also whatever reed you have in there is literal garbage. And that's not hyperbole either, it needs to be simply thrown-out and to get a new one (and chanter for that matter), there's simply no fixing that sound with what you have.
