No, it isn't. I think this may be a translation thing, but where I come from, an "average" of values is equal to the sum of all of the values, divided by the number of values, whereas a "weighted average" assigns an additional term, a "weight" to some, but not all, of the values, thus evaluating the values unequally for the purpose of some bias: For instance, a weighted average score of a single player's per-game kill counts, with more emphasis, more weight, given to his more recent games, because players tend to improve rather than regress, so more recent values are more representative than older values.

Thanks for the clarification. In that Last case, I would have used 'biased average' - I think I've seen it used at least once , but maybe it's uncommon usage - or is it used for yet another kind of 'average'?
