If a martial arts class has very few students or barely any, is it a scam?

I heard that happening once 3 years ago during the pandemic. Still, wouldn't there be at least 15 students?

In the training it was just the Sensei, the student and the Sensei's best friend who happens to be the owner of the place. The place was originally a small school for kids, then it became a gym and lastly it was growing into a Judo class. Was that person scammed? Plus, after a full year she was still at just white belt. If no one is coming to a martial arts academy and the student isn't advancing after a year, is that a scam?

She applied applying what she learned as a playfight and someone that's an expert ended up showing her everything she's lacking and her blocking techniques wasn't that good either.

[AI Opinion]

It's not necessarily a scam if a martial arts class has few students; small classes can offer personalized instruction. However, concerns arise if the student isn't progressing, especially after a year, or if there's little transparency about the curriculum. Belt advancements depend on the school's criteria and the individual's commitment. If the student's skills don't improve in practice and the instruction lacks depth, it may be worthwhile to reassess the school's credibility and teaching methods. Research the school, speak with past students, and consider other reputable classes.
