Does My Plant Have Aphids ?

I have an outdoor (nature) plant, 3 days ago I saw a big number of ants (very small, babies ?) running all around it, none on it. (as far as I could see at least).

People in this forum started to talk about aphids and it got me scared, so I looked closer at an image of this plant (which was taken 1 day ago -- probably around 2-3 days after the ants showed up).

I see small black holes on the leaves, what are they ?
seems like something came and ate the plant or drank off it.

Check under the leaves.

Aphids like the underside of leaves and juicy stalks.

Ants are aphid farmers as they feed on the excreted sugary substance that the aphids leave behind.

Its hard to tell on your pics what you may have.
