It means the Naval Academy is aware and can see the candidates who applied to NROTC. With this call, someone assigned a recruiting task has reached out to advise you could be a candidate to apply to the Naval Academy as well if you are interested in doing so, and haven't done so already. It does not mean more than this, or less without further data. What he says when you speak will be important. Are you interested in attending the Naval Academy? if so take a minute tonight to be informed about what the academy is as needed, and then call him back tomorrow with the details of your NROTC app in front of you, and see what happens. You mentioned previously being a high level athlete - is it in a Division sport or 2 that you could play for them? That could help. Good luck.
