Not only does it say barely nothing, this is a surface-level misinformed take with no references for most of the claims and references to maybe 5 studies. Reading a handful of studies in this field is completely meaningless. If you want to actually learn how to build muscle you can consume say Mike Israetel's content. As for "good genetics" in the article; Top bodybuilders generally mean with "good genetics" that your body's response to steroids is good. It does not mean that you naturally are an average person and by some magical reason respond incredibly well to training and eating because your genetics are "good".
