There appears to be no limit, but are you an outstanding pop singer or someone who tight-rope walks over chasms? No? Then first work out what people will pay money for. Yes, there's music, number one preference for many. But what else? What do you have to offer or must you copy someone who's been very successful and try to repeat that? Viewers want videos and most do not contain ads, so advertising is less likely to earn for you than capturing the ideal video, or realistically, sets of videos.
Roughly speaking, if your video gained 2000 views PER DAY, you might expect to get $10,000 in a year, but that implies that people would have to retain interest in that video day after day, month after month. Is that likely? Tight-rope scare, yes perhaps, but a topical video will quickly pale. It would be wise to follow the fortunes of videos like the ones you think you could make to see what your chances might be.
