I received an email from the prof after sending an appreciation email after taking multiple courses with him and idk if this is just a rhetorical message or just a polite rejection email 😭 I quite talk academics and been talking in person with him and idk what is inside in his brain😭

"Hi, _____. Hope you're well after the final. I see a huge potential with your insight on this field, which is quite decent. You've always demonstrated strong understanding of course material with your research skills, which interest me. They, however, are slightly less than my standard. As I've been observing your grades and depth of your knowledge, I'm happy to answer your email about my research. I'd recommend staying bit longer on Campus to strengthen your skills, if your time and budget permit. See you after taking a rest."

(I paraphrased the content cuz I don't wanna reveal myself here)

I didn't ask a research favour by email beforehand, but casually expressed interest in person once. And i've seen him ghosting emails from students whenever he doesnt want to reply email and he heavily prefers to do that (regarding the grade curves and whatever) and this quite confuses me😭
