You may be complaining the other day 1000 but in my own opinion your doing a damn good job better than me and with my radio station for example I shoot out $30USD a month on Facebook ads, made my stream public on every platform I could on the internet, pay 16.50 a month to the host and $200-$300 a year and I only get maybe 1 listener every 11-12 hours if that,
Your lucky you got the followers in my own opinion you should not complain because you got more YouTube Subscribers than most YouTube channels out there to my knowledge given how much competition you have on YouTube,
My advise is work hard and don't give up at it, be funny, and try to express your maximum creativity on YouTube and don't be shy to run ads but I will tell you this my ads on Facebook are a complete failurealso keep an eye on your views because according to my experience with ads on Facebook a lot of people are click bots, or run fake accounts because turns out I get likes but no listeners. Most people just click (like) on my Facebook ads then never even tune into my radio station and it really pisses me off because I pay for those ads and all I get is lousy fake likes
(edit) I know your probably laughing at me but I just thought I'd cheer you up and give you some insights on running ads, looks like your getting the views as expected so whatever your doing it's working
