It is, and it isn't. You shouldn't need that much RAM, but if you have it
it _will_ eventually be used. You probably aren't using any of your swap.
Any good swapper will ensure that your memory utilization is close to 100%
before swapping anything to disk.

I would really suspect htop. But compare both to "free".
