Create youtube ads to re-targeted my audience

Hello beautiful community!
I’m Damian Ruiz, I have a multi-award winning educational content channel (1,100,000 followers).

Currently more than 45,000 people have downloaded Brave through my channel.

I noticed that I have a lot of US traffic (11%) so my question is as follows:

Can I make youtube ads re-targeting my audience?

Obviously I wouldn’t use any keywords like “brave”.

Thank you very much for your time.
