On the one hand, as has been said, not every clan is going to have children in the same age brackets.

On the other hand, we know that many clans in Konoha have far more members than we typically see, with many clans displaying members in the midst of the Fourth Shinobi World War that were previously unknown and given that these are in fact ninja clans, even with the shift in economic balance of the world, it seems unlikely that these people, if only as a token to tradition, wouldn't go through shinobi training.

To put it bluntly, there's so many Aburame, Sarutobi, Hyuga and all around that there should be at least one of these clans in every class.

Now while Boruto is of the Hyuga line and fills that gap despite being very atypical of one, it seems strange that the only thriving clans of the village representant in their class are him and the Ino-Shika-Cho directly related to the previous generation mains. Even if they weren't stand out characters like Sumire or anything, you'd expect at least one of the other big name clans to be there.
