I've Got It
Are you talking about the suggested channels on the profile page?
Anyway, I don't think just subscribing will help much. However, ENGAGING in the community of a big Youtuber will! Get involved in their comments, events and social media and people will start recognizing your name at some point. I'm not saying you should spam comments all over their videos, but I'm talking about activily contributing to their community.
I think you could make relevant comments on their videos (not comments like "check out my channel and such), could help you get some traffic! I have made some comments on a Matthew Santoro video and one person came from that and subscribed to my channel.
I agree with what Dutchie in England and TheSwedishTraveler have said above.
One time, when I engaged the gaming live stream chat section of a much bigger channel than mine, I noticed that I had more views on my videos and a few more subscribers after his stream was over.
So, I can tell you that this strategy works totally works!
.Later my cool dudes!
