Body fat % is more accurate than BMI when it comes to gauging health risk, but it is also a lot harder to estimate/calculate so BMI is generally used to estimate risk factors. This is a problem will all BMI-based metrics, and it's worth noting that BMI is not one-size-fits-all. Different body types (muscular vs lean, for example), different ethnicities/cultures, different genders, all have different definitions of a "healthy" body and BMI isn't able to take all of that into account. That's not to say that it can't be useful, but take it with a grain of salt when it comes to interpreting BMI across different fields.
