Dude spend enough time on YouTube and you'll see the smallest channel grow,
Let's say you use a bot, then what?
You're here on this site to come up with ideas, brain storm, see if a particular markets saturated, those that come here to bot are in short falls.(yeah I have YouTube channels that are dead, but some growing)
Dude trust me the only thing worse then a bot is lazyness, feel pumped, get in the mindset that your times here, find a hammer and chisel and search for something trending(a song, then reedit it, make it asmr what ever)but it must be viral.
Look for YouTubers talking about shit going viral: penguin0 meat canyon, they focus on things that are viral.
Then once you have a idea shoot your shit.
