VGC has Europe at 10.09 million units as of September 21st. So, they're overtracked by roughly 200-300k units.
When Nintendo give sales figure like this though they're kinda crap. As in they never use decimals. Without knowing the date this figure is for (1st october? 8th october?) and assuming it's probably rounded we can't say whether it's overtracked or not.
The only thing we can say is it's definitely not undertracked, which I believe some people said they thought the switch european figures were.
Unless we get more information may as well assume that VGC figures are correct.
