Funnily enough, the UK had this problem about fifteen years ago.
Everyone was wringing their hands madly and talking about things like mentorship, and how the education system was inherently racist (and, unfortunately, always making implications about how white people were all racist and this was a deliberate outcome) or certain groups apparently having no fathers.
Fifteen years later, and black kids are more than twice as likely to go to university as white kids...funnily enough, if you mention race when you talk about this now...you get called a racist (it turns out, some people just really think race is the only thing that matters).
Either way, stop talking about race. It doesn't help. It is incredibly disempowering to have someone supposedly help you by constantly bringing up the fact you are different. And, shock, if you do this and things improve those children never stop banging on about race and think everything is rigged against them (in the UK, there is no black wage gap...if you mention this, you will get excoriated). Definitely, culture does matter (this just has no relation to race though) but if you create an environment of success then this can be overcome.
The US is the archtypical example of how not to do things. Six decades into civil rights, and the same people are still banging on and on about the same stuff (I will get trashed for this but in the US, this kind of grief mongering has almost become an industry in itself...you can see why it will never end, the vested interests are too powerful).
