It’s not “technically correct.” It’s just correct, and what you said was incorrect.

Interestingly, a slightly higher percentage of White people smoke (12.9%) than do Black people (11.7%). And yes, 81% of Black smokers use menthols, while 34% of White smokers do. So the point is the same. Banning menthol cigarettes does impact Black people more than White people.

However, the very next paragraph seems to balance things in the other direction:

People who smoke menthol cigarettes make more attempts to quit smoking than those who smoke non-menthol cigarettes. However, the proportion of people who tried and succeeded in quitting non-menthol cigarettes is greater than the proportion of people who have tried and succeeded in quitting menthol cigarettes. This could be due to a number of factors, including the way in which menthol enhances the effects of nicotine in the brain. African American people who smoke menthol cigarettes may be even less successful in quitting than other population groups. Black or African American people can face barriers when trying to find and use proven quit smoking treatments. Also, the conditions in which non-Hispanic Black people live, learn, work and play may make it harder to quit.

The point remains the same: banning menthol cigarettes does impact Black people more than White people. In a positive way. Reading further (I won’t quote the rest, there’s a lot), it’s clear that White people (men in particular) are the least likely to smoke menthols, so banning menthols literally helps everyone else more.
