It's pretty simple.
Let's take the 2019 numbers you posted.
Per US census estimate of 2019 - 328 million people in the US/76.5% white/13.4% black/10,1% all others
370 whites killed in a population of about 251 million (76% of 328) equals 0.000148%
235 blacks killed in a population of about 44 million (13% of 328) equals 0.000534%
So blacks are killed at a rate over 3.5 times (350%) more than whites.
That's inequality and more likely prejudice and racism.
