I don't think it's a matter of not being good, just that others are that much better. It might sound similar, but it's not. You're still better than hundreds of thousands, or even millions, of people.
It's like being a tech worker who earns $400k a year and saying "I don't earn that much, there's people who do what I do clearing seven figures a year, and others who were able to retire in their early 30s and don't even have to work anymore because they became so wealthy from work." Sure, it's not a lot of money compared to those people, but it is when compared to the vast majority of wage earners in any region in the world.
