no, the macros don't matter for fat loss, particularly when you're starting out. the 1800 calories per day are what matter. assuming you're a guy, at 5'10 and your weight, that's a pretty huge deficit. you'll lose weight. in fact, i would recommend increasing calories on certain days to keep the metabolism guessing a bit, so to speak. a caloric deficit is not measured in hours, or even by the day.
that macro split will almost certainly put you into ketosis. you don't have to do that, but if it keeps you feeling full and you're feeling good, it's totally fine. the fat in and of itself is not a problem, and will not prevent you from losing fat. if you want to eat more healthy carbs, you can do that too, and back off the fat a bit. it's just a question of what keeps you feeling well-fed, and energetic.
