I have a small gap between the coping and the tile. The problem being if we have a heavy rain and I don't catch it water goes into that gap under the deck. Over time it can erode under the deck causing it to collapse. My question is can I seal that gap or is it there for a reason

I also have what looks like a foam piece that sticks up between the coping and the deck.

It can also erode behind the wall of the pool itself. Never overfill or allow the pool to be flooded above the waterline tile, it can cause serious structural problems.
A picture may be helpful so we can see what you are looking at. You can use photo bucket to add pics.

My neighbor said they are supposed to grout between the coping and tile.

You could try and match the color with caulk that expands better than grout. Like they said don't let your pool over fill.
While that is not a very large gap, I would seal it with polyurethane caulk.....readily available at the big box stores.
You could also likely ignore it as I don't think that's big enough to cause any issues.

Over time, polyurethane in that exterior situation, will outperform silicone by a pretty good margin. Your call.
I forgot this caveat, poly is NOT water soluble so will be harder to work with but it also doesn't have that plastic "gloss" that silicone has.
Additionally, you can often find poly in a "sanded" version which makes it look pretty close to grout.
