Coronavirus, school lockdown and future uncertainty
“don't worry about graduation, you will be able to graduate online”


In this context, I would translate your advisor's thought process as:


  This student sounds like they are anxious and worried about graduation. The best way I can help them worry less is to simply tell them not to worry.


Nothing there about wanting to meet or not. Indeed, if your advisor does not want to meet in person, it's more likely to stay out of the public and help contribute to reducing disease spread.

I think it's fine to write an email with some bullet points about things you'd like to discuss further. Thank them for reassuring you about graduation, but make it clear that there are in fact things you could use advice on besides just a path to graduating.

Then you can ask whether the professor would prefer to discuss those things over email, to meet via phone or video chat (like Skype, Google Hangouts), or to meet in person.

Be as patient as you can be, because this is likely a stressful time for everyone. Your advisor may not be able to meet or respond right away - don't let that worry you.
