Any helps on how to grow a YT gaming channel?

Hello,

Since I like playing Competitive online multiplayer game (Warzone) I've decided to create my gaming youtube channel. I will post weekly videos with a review on all my kills in the game. (I spend much time watching such videos when I am bored)

I need to reach 1000 subscriber, and this is my first try on video plateforms.
Any helps should be very valuable to me.
