H1B interview today, they kept my passport, am I approved?

I had my interview this morning in Vancouver, Canada for H1B. Many questions. They kept my passport and said I would receive by courier in 3-5 days. Does that mean I am approved? I did not get 221g or statement of denial. I did not get statement of acceptance. Officer just said 3-5 days and turned and walked away. Confused, anxious and stressed. I thought this would be a relief today and it is just more stressful.

If they kept your passport then it means you will get the visa in 2-3 days.

Btw , how many questions did they ask you ?
