Not really no, you can both bet on fantasy sports and regular sports and honestly if you were in it just to gamble, then you being counted out from traditional sports gamblers isn't really a negative since, well, you just placed yourself in your actual placement. Regular sports gamblers enjoy gambling both because it's a gamble and because the players involved are people you know (and possibly love/hate) due to watching them all the time and just in general enjoying the process of them playing the sport itself.

And I'd only ever consider an activity as gambling if money was involved. If it wasn't, then it's not gambling, it's gaming.
