He's not right:

While people of color, individually and as groups, have been helped by affirmative action in the subsequent years, data and studies suggest women — white women in particular —
have benefited disproportionately. According to
one study, in 1995, 6 million women, the majority of whom were white, had jobs they wouldn’t have otherwise held but for affirmative action.
Another
study shows that women made greater gains in employment at companies that do business with the federal government, which are therefore subject to federal affirmative-action requirements, than in other companies — with female employment rising 15.2% at federal contractors but only 2.2% elsewhere. And the women working for federal-contractor companies also held higher positions and were paid better.
Even in the private sector, the advancements of white women eclipse those of people of color. After
IBM established its own affirmative-action program, the numbers of women in management positions more than tripled in less than 10 years. Data from subsequent years show that the number of executives of color at IBM also grew, but
not nearly at the same rate.
