Started texting a guy who is doing a PhD at university and he said he is very busy with it, is he hinting he is too busy for me?

I recently started texting a guy I met (I initiated). I asked him about his hobbies and he texted back saying he’s very busy with his PhD and he hasn’t got the time for hobbies. I’m not sure if he’s hinting that he doesn’t have the time for me🤭 what do you think?
