how can I market my drop shipping

Look I know me being 12 is kinda young but I really need this money for my fam and to make it out of the hood

What up, my name is Kosta and I plan to start consistently posting content on my youtube channel (linked). My channel is in the fitness and lifestyle niche and was wondering for tips to grow my audience and come up with ideas for content. I recently got a bunch of new equipment to make my videos higher quality and more entertaining, after saving up from my job. Im 18 and would like some advice on how to reach a point where I can monetize my passion for making videos. https://youtube.com/@kostadinokottaras?si=56YMkPEfdRB5bXiN
