Can you still gain fat if your eating around 1.5k Calories a day?

Yes. Calories is Calories. It doesn't necessarily matter where the calories are coming from when you're dealing with weight loss and weight gain. It's like asking is a pound of brick or a pound of feathers heavier. In either case, you have a pound.

You didn't talk about your height, weight or body composition, so I can't make an assessment on whether 1,000-1,500 calories is a good range for you.

If you're consuming 1,500 calories each day and your body only uses 1,000, then you're going to experience weight gain if this occurs everyday. In contrast, if your body need 2,000 and you only give it 1,500, then you're going to experience weight loss overtime.
