Youtube monetization (Reused Content)

Hello, I am new to the Envato platform. I have a small youtube channel and I recently bought a few songs and videos from videohive and audio jungle. I spoke to someone that has a similar channel as mine and He said that if I purchase videos/music from sites like these. Youtube will not monetize my channel because other people have the videos/music already on their channel. Is this true? I am really stressing about this because I really don’t want to delete all of the videos in order for youtube to monetize my channel.

That´s not true. Don´t worry about that.
