Yes, music copyright on YouTube is often a complex issue. For a song, there may be different copyright owners, including the songwriter, record label, and singer. If a video is uploaded to YouTube and uses the song, a copyright dispute may arise.

If YouTube believes that this video violates copyright, it may be deleted or placed in restricted viewing status, making it impossible to make money. If the video could remain on YouTube, it might not be able to make money through advertising revenue.

However, making money on YouTube is not something everyone can do. Only videos that meet certain conditions will have the opportunity to earn advertising revenue. If you want to make money, you need to first meet the conditions for making money from YouTube's advertising revenue. Generally speaking, only videos that meet the following conditions have the opportunity to obtain advertising revenue:

The video quality must be good and must not contain illegal or social moral content.

Videos must be original content and cannot be plagiarized or copied from the work of others.

The video must have a certain number of views to have a chance to earn advertising revenue.

The number of subscribers to the video must also reach a certain number to have the opportunity to obtain advertising revenue.

If your video meets these criteria, you may have the opportunity to make money through advertising revenue. However, due to copyright issues and other reasons, advertising revenue may not be obtained.
