Basal is the amount of calories needed for your basic body function. If you lied in bed all day, the basal amount is what your body would "burn". The other numbers are the additional calories your body uses as part of living your daily life - working, chores around the house, running errands, etc., and then there is the additional calories you burn during a workout. So according to your stats, you took in far fewer calories than your body used today. This is great, although you need to be careful of making sure you take in enough calories. You want to shoot for taking in around 500-1000 calories per day less than your body needs to lose 1-2 pounds per week. In your case you are well over that 1000 calorie defecit, which is fine for one day, but doing this regularly will actual kick your body into starvation mode, and your metabolism will slow and you can lose muscle. Given your weight and basic caloric needs, you should shoot for at least 1600 calories day - and safely lose 1-2 pounds per week without damaging your body.
