I think this falls under "ignore those people".

There's a lot of well-meaning beginner advice like "fill the frame!" and this "make sure there's a dominant point of interest". A point of interest is simply what it says — a point that attracts your attention — and a dominant point is one that is obviously the focus of the picture and makes the intent of image easy to instantly grasp.

This is designed to give your photo "pop" and instant wow. That may be important for stock photography, and it's certainly the right thing if your point is to simply say "hey, look at this thing!" It probably helps you win online photo contests.

But it doesn't necessarily make a great photograph. A good composition should encourage and reward exploration, and the viewer should want to take a few moments to take in the detail. If the photo is obvious, it's also easy to put aside.

Your image photo is simple, without a lot of extra bother, and I think each element has a part to play. There are, in fact, many points of interest, and while none is dominant, they work nicely together as a whole. I like the sequence from new to old, and I like the balance of the bright burning candles and the unlit, "waiting" candles in the dark. That adds both story elements and is nice visually. And the match — a catalyst. To me, this tells a story (the story, maybe — it's about life and death!). The composition is great, and I wouldn't cut anything from it.

If an image has many different points of interest and they're not connected, that's just clutter and should be rethought. If there were random items in the background, for example, you might want to reconsider.

On a technical note, it might be nice if there were slightly more depth of field, so the match would also be in focus. I can think of a few other technical and compositional comments too — but I think you're spot on with the interest of this photograph.
