Well i listed 2 activities, you could certainly add more to the test. Just as we add many questions to an IQ test.
Even if the test doesn't predict performance in every single sport, that doesn't mean it has zero predictive power in all sports.

Similarly, I'm not saying IQ is destiny or even the largest factor in any given endeavour, its not. But its equally wrong to say its not a factor at all. It is somewhere in the middle.
Like most metrics, it doesn't capture the entirety of the squishy concept as you say, but it does capture something about it.
I think we understand this in many other areas. Look at PE ratio or revenue growth for a stock, look at goals on target for a football striker, VO2max or running economy for a runner, mileage for a car. IQ is understandably more controversial but the concept is the same.
