Calories counters are put on treadmills, ellipticals and bikes for one reason only - to sell them.
Usually calories counters just measure how far you've gone and mutlply it by your weight and a scaling factor. This is what you saw.
All CV machines are there to improve the strength of your heart and blood supply system and in the same way that you lift heavy weights to improve strength - you must run fast in order to improve CV capacity.
If you are going to lose weight in a sustainable way then you need strong muscles and a good CV system.
When people are heavily over weight then these crude calorie counters provide a level of emotional support. Once you get within 10 pounds or so of healthy BMI you see that these counters are very very flawed.Your body becomes more efficient, you rest better, you can jog for miles and the calories just don't seem to "burn" etc.
It is easier not to eat the calories than to attempt to burn them off.
One thing you might try is this.
Walk 600 m and wait for 24 hours and see how your body feels.
The following day sprint ( I mean sprint!) for 100m, walk the next 100m, sprint the next (full out!) walk 100m then srping the final 100m.
Technically you have used less calories than during the first "walk"
However see how your body feels the next day. If you have gone full out three times then you may even find it difficult to move. Completely different (and beneficial) process are involved in high intensity training.
