There's lots of similar programming videos, does that mean you should not learn programming because you'll be the 3 millionth fish? Competition exists in every niche, you still have to get better than others, there's no silver bullet.
If you learn programming you can create a completely unique and useful program. Dropshipping on the other hand is thousands of different people selling the exact same product, there is no value added.
Tbf, from the economical perspective both are a lottery of marketing.
Interesting and scary take.
My opinion is that you one hundred percent should not learn programming from YouTube videos. It is tremendously ineffective.
