Went to interview and left without decision

Hi my husband and me just went to the interview today. The officer told me to look at a camera and took my index finger prints. He asked us a lot of questions, and I didn't know the answer for 1 question. He kept our bank statements, phone bill, life insurance and 1 picture. At the end, he said everything seemed to be good and if they don't need anything else, I will get my green card within a month. So, does it mean my green card is approved? He didn't stamp anything on my passport, didn't give any papers, and said that we just needed to go without doing anything. I'm so panic. Please let me know. Thank you.

When I went to my interview two years ago I didn't get an answer the same day. I didn't get asked many questions as you did but the officer told me the same thing, that they would review everything and I should get an answer in the next 30 days. My status changed to approved the next day
