Excellent. Either you got this training at some point or you figured it out yourself. The point of such training is to make sure that all of us white men understand that benefits we've gotten from systemic racism.
This is not really different from other aspects of education. I spent plenty of time in computer science classes where I already understood the material. I had some exposure to this kind of education about systemic racism early in college, which I completely bounced off of and missed the point of. Future exposure eventually got the message through. Sometimes repetition is needed.

That's a big "aside from". There are many times in my career where I have decision making power or influence on a decision that involves other humans. Being aware of systemic racism and unconscious and conscious biases help me make more equitable decisions. If you are doing similar things, then congratulations, you are probably helping solve the problem. I don't think anyone is asking you to do more than that.
