99% genetics and the rest is hard work and diet...come on, you can't deny that?!

Debussey thinks the 99% thing is a bit of an overstatement for the most part.
Debussey thinks that as in most areas, there is a "threshold" of "genetics/talent" needed to be had in order to have a chance to succeed in the first place. If you're a freaking moron, mongoloid or whatnot, you will not be able to master areas like advanced physics or mathematics, no matter how much you try. But if you are above the "threshold", you can succeed (the further above the threshold you are, the easier it might be to succeed).
If you are one of those unlucky bastards that does not have enough talent to succeed in BB for example, then genetics = 100%, because no amount of work will help you.. But VERY FEW people are so "genetically impaired" that they can't improve their body.
Of course, when you get to the upper-echelon of competitive bodybuilding, the "genetical threshold" becomes higher and higher, and very few people can compete in those upper levels regardless of what they do (thus, genetics = everything for them), but if you take an average of all people BB'ing out there, the "genetical threshold/cutoff/whatever" = not that high (most people don't aspire to be Ronnie..), and a big% of people are "good enough" to have a chance to meet their goals.
If you are "good enough", remember that attaining a muscular and defined body requires getting the body into a certain state of body composition, and except for a chosen few, it does take effort. Muscles and burnt fat won't come by itself. A few % might be super-talented and able to get by without doing shit, but many more can get that nice body if they put in the work.
Again, genetics will still be an important determining factor for the output (results) of the input (work), but to say that it is "99%", given that one is above that "threshold" = an overstatement. Very few % of the people capable of getting into good shape out there get into that shape without the work..
Haha, just like most things in life, the bell curve strikes again
