That's not the only point. You are confusing necessary and sufficient conditions. Being able to do the thing that needs to be done at the right time is a a necessary condition for this success. It's definitely not sufficient condition as you rightly point out. You note that you use fiverr and development teams you've worked with before to deliver quickly. Without that you have nothing to deliver or it is beat in the market by the time you figure out how to make it. An influencer isn't going to magically create products for you.
