Sure. It implies his success is because of his race. It also implies his bad behavior is because of his race. Both of these statements ignore his agency and individuality, and suggest white people are, as a group, poorly behaved and undeserving of the success they work for.
Attributing negative stereotypes to people based on group characteristics is bigotry, and doing so based on race is racism.
Imagine it were attributing his succeed to being jewish, or his bad behavior to being black. It should be pretty obvious that those would be socially unacceptable. The fact that it's currently popular among some groups to hate white people doesn't make it any less racist.
