If by "competitor" we mean "everyone who competes in the sport" and not just "everyone who competes well enough to qualify for the Olympics" then yes, Olympic athletes frequently perform 10x better than some of their competitors.
Please name a single sport where the world record is 10x of what average hobby athletes perform at.
To show how ridiculous that idea is, that would make "average" 100 meters sprint times more than 1.5 minutes, and "average" long jump distances less than 1 meter.
Fencing. I’m a “hobby athlete” at fencing (Sabre) and I’d play with about a 10x point multiplier if I wanted to compete with an Olympic level athlete. We had a couple people like that at our club.
That's comparative performance vs. absolute performance. Yes, there are people who can beat others 10x more often than those others can beat them. That doesn't mean they perform 10x as well. In fact, it can be enough for them to be just slightly better in order to achieve such comparative results.
Where absolute performance is concerned (that is, performance measured against an external, objective standard), no elite athlete in any sport is anywhere close to 10x'ing their hobbyist peers. Even beating them by a factor of 2 is unthinkable in most sports.
