The cameras go well beyond the stated actuation. I've seen reports here of 200,000 releases. Whether it is 3000 or 9000 is probably not very important - both numbers are at the extreme low end.
There are some activities that create multiple actuations - such as using Live View.
There have been some stats on failure. In general, between 1000 and 70,000 would be random failure with equal opportunity for failure regardless of the shutter releases. At the 70,000 and up level you start to see a higher incidence of failure but those cameras have also been used hard and may have other contributing factors.
I'd view it like miles on a car - below 70,000 releases it is relatively unimportant.
