No, it absolutely is not - the opposite actually. F1 history is full of mediocre drivers getting catapulted into top spots by rocket-cars, only to fall back into mediocrity once competing teams catch up on the engineering.
It's also why everyone knows that, outside the 2-3 top teams that dominate the table on any given year, the real competition is between drivers in the same team, because it's the only fair fight for drivers (since both have basically the same car).
Driver skill is definitely a factor, don't get me wrong, but F1 is 95% about the car.

I'm not denying motorsports are dangerous - particularly F1 - but it has become much, much, much safer over the past 10-15 years.
It's like saying that because of the new high tech swimsuits and caps, the olympics is a contest of clothing superiority. Technique is still king, but a couple percentage points of advantage from your equipment is absolutely huge at those levels.
