Why do some people not agree that "White people in the U.S. have certain advantages because of the color of their skin"?

This Brian Schaffner post at Data for Progress indicates that, on 9 June during the 2020 protests over the death of George Floyd, only 57% of Whites and about 83% of Blacks agreed that "White people in the U.S. have certain advantages because of the color of their skin". It might be worth considering why not everyone agreed with that statement.

Let's check data from the Nationscape survey, focusing on the survey conducted 11 June 2020 (two days from the aforementioned Data for Progress survey) and the items that ask: "How much discrimination is there in the United States today against...", with response options of "A great deal", "A lot", "A moderate amount", "A little", and "None at all".

For rating discrimination against Blacks, 95% of Whites selected a level from "A great deal" through "A little", including missing responses in the 5%. It could be that the difference between this 95% and the Data for Progress 57% is because about 38% of Whites think that discrimination against Blacks favors only non-White non-Black persons. But the 57% Data for Progress estimate was pretty close to the 59% of Whites in the Nationscape data who rated the discrimination against Blacks higher than they rated the discrimination against Whites.

The pattern is similar for Blacks: about 83% of Blacks in the Data for Progress data agreed that "White people in the U.S. have certain advantages because of the color of their skin", and 85% of Blacks in the Nationscape data rated the discrimination against Blacks higher than the discrimination against Whites. But, in the Nationscape data, 98% of Blacks selected a level from "A great deal" through "A little" for the amount of discrimination that Blacks face in the United States today.

So this seems to be suggestive evidence that many people who do not agree that "White people in the U.S. have certain advantages because of the color of their skin" might not be indicating a lack of "acknowledgement of racism" in Schaffner's terms, but are rather signaling a belief closer to the idea that the discrimination against Blacks does not outweigh the discrimination against Whites, at least as measured on a five-point scale.
