As others have mentioned, as far as Youtube is concerned, likes and dislikes both help promote your video within the algorithm. Ever since those clickbaity "DO NOT CLICK ON THIS VIDEO" followed by "DISLIKE THIS VIDEO"? I've seen a few with like 5k dislikes and less than a 100 likes. I guess the algorithm sees that as a "controversial" video to promote.
But don't worry about it. All of us, even those that have millions of subscribers get dislikes. Be ready for it. Whereas right now a couple of dislikes might seem discouraging, say your channel grows a lot in a year, you reach 50k subscribers, and you average 5k views per video. Now you are facing potentially anywhere from 50 to a 100 dislikes (just an example). Those with millions of subscribers face thousands of dislikes. Why those people dislike the video, we would all love to know. So don't let that discourage you, it's a normal thing and I also felt that way when I started getting my first dislikes.
4 months later, and my stats are at:
2651 likes
166 dislikes
You can expect a similar ratio.
