Not at all, they are from like, 2002. You can find sealed ones on eBay, they're pricy, but quite worthy as they resemble che characters quite a lot. Unfortunately, Palisades, the maker of these toys, went out of business.
Oh, that bites. It's really odd that I never saw them, though - 'cause I was living in America at that time (though became a fan of the series a little bit later, if I recall correctly). The only IZ merch I'd ever seen was plushies, keychains and t-shirts - until recently, seeing homemade plushies and the like here on DA. I will have to check eBay, though! I always wanted IZ figurines.
Also, when you first mentioned Invader Zim, I thought it was going to be something quite meh and unfunny, some, if not most of the shows you have introduced me, are not my type, so I admit I ignored it when you bugged the shit out of me to watch IZ, apparently I was wrong lolz.
You linked me to the first episode, I found the rest on my own XD.
