Youtube How?

Hello , I need some help with understand how this Youtube thing works

I am newb and I have some idea that I would like to make some videos and post on profile so I can share with people in
my country that I think will be interested in watching them. and also might be streaming ocasionally

I dont understand how I can reach people on youtube to stand a chance
that somebody comes to my channel and see the video and then decide if he likes it,
I see so many youtube channels with so many subscribers and viewers and how do I who have no
subscribers or viewers can reach anyone.

I see that on my "niche" when I write my channel name there is no others similar, only me so its kind of unique. So thats good


I dont want to get 10000000 subscribers or 100000000viewers, I just want to try reach 100 views or 100 subs for start and maybe few hunders more later so I can kind of taste the waters and see how it functions.
Where do I start and what I have to do so to make first steps from zero to... something

Share it on social media, if your videos are good people will start sharing it!

Brand yourself on all social media platforms (Facebook, Instagram, Twitter, LinkedIn, etc.). This way you'll have presence not only on YouTube and will be able to deliver traffic to your channel by sharing your videos on each platform. Consider creating quality content, useful and engaging posts. Having your own website is also a big advantage. Don't get discouraged by the big players in the game, since you have your own unique idea.

I will try, thanks
