No, it's exactly like kangaroos. /s...

My point was that it is nothing like in kangaroos. The comparison is just misleading.

It's like kangaroos in the sence that it's a pouch not a uterus. Some fish put eggs in a cave, but that doesn't make the cave pregnant.

Pregnancy has been traditionally defined as the period of time eggs are incubated in the body after the egg-sperm union.[1] Although the term often refers to placental mammals, it has also been used in the titles of many international, peer-reviewed, scientific articles on fish, e.g. Consistent with this definition, there are several modes of reproduction in fish, providing different amounts of parental care

Going off of this, it's just a matter of the term "pregnancy" being co-opted to describe something completely different from what it means in its original context. As does happen, even in science.
