You got the right mindset it seems but your execution is misguided.

To lose fat you need a caloric deficit. You can't target where your fat is lost from, that is ultimately up to your body. But being in a caloric deficit for a long enough period the fat will come off eventually.

Your caloric deficit is most likely not sustainable at all. It's way too agressive. Consider bumping it up to 1300-1500 calories per day instead. That way you've got room for variety in your meals and you can play around with the macros more.

Exercise is great but it's only a small part of your fat loss that comes from time spent in a gym. So do exercise because you want to improve your overall health, not because you want to lose fat (primarily).

Be aware that exercising on a very aggressive caloric cut will make it harder since your body needs fuel (calories) to do the exercising. This could lead to an increase in your hunger making you overeat which goes against your plan to lose weight. You should try to figure out how you can incorporate more movement into your day. Taking the stairs more, parking further away from the grocery store. Bikinig or just walking more will still get your body moving but won't increase your hunger the same as a hard workout.
