Whatever the intent, it seems a poorly worded statement.
If you mean to say that everyone holds racist views, however small, even at a subconscious level (due to inherent human tribalism and societal conditioning), then it's something that extends beyond "being white".
I'm sure a black person will have prejudices against an Asian one and vice versa, for example (this is of course proven by the fact that racism is very much present in countries like South Korea or Japan).
If you meant to refer to institutionalized racism, then it's something that varies from country to country, since a white person will likely not have the same advantages in Japan , as they have in the US, for example (though they'll still probably fare better than other ethnicities, unfortunately).
I don't think pointing out how everyone can hold subconscious racial biases, or how whites are privileged in many developed countries, is anything controversial, but the way the statement was worded is just confusing, and comes off as either inaccurate, or reductive.
EDIT: That said, people should stop thinking in terms of someone either being or not being racist as an absolute.
There are racist thoughts, racist words and racist actions, all of different magnitudes.
You just have to keep watch and root them out when you spot one (or somebody points it out to you), instead of thinking that saying or thinking one racist thing will put you on the bucket list and, therefore, you can't be racist because you don't hate other races, and aren't nearly as bad as some people on said list.
It's more nuanced than that.
This applies to Sexism as well.
