You also need to take in account that when Harry was born, that’s when lots of families were massacred and people were at war so there weren’t that many kids. We also know these things only from harry’s Perspective from the Gryffindor house. We don’t know it was for other houses and years. Also, when he was watching snape’s worst memory, he was in a dada owl exam and he noted that there were over 100 students. That would mean over 100 stein sets in one year, a big contrast from what you mentioned above. I’d guess that after the second war, there would’ve been a lot of kids born and that the year sizes would be much bigger
