It's not that.
Calories in and calories out.
but many people don't realize
calories in affects calories out.
Let say your current metabolism is 2200 calories a day based on your intake of 2200 calories a day.
So you reduce to 1700 calories and get 500 calories deficit. What happens in the long term.
week1 -- calories in=1700, calories out = 2200 deficit = 500
week2 -- calories in=1700, calories out = 2100 deficit = 400
week3 -- calories in=1700, calories out = 2000 deficit = 300
week4 -- calories in=1700, calories out = 1900 deficit = 200
week5 -- calories in=1700, calories out = 1800 deficit = 100
week6 -- calories in=1700, calories out = 1700 deficit = 0,
<----- At this point no more weight loss and this is where most people complain that they are no longer losing weight. Body metabolism have adapted to low calorie diet.Now what happens when you start to eat 1900 calories which is still lower than your original intake. ... then you gain weight despite eating less than what you originally eat.
Your calculation is correct but that's not metabolism adaptation. Its just your bodyweight dropped hence doesn't require that much energy to move.
So when your bodyweight dropped, then you need to recalculate the TDEE. Simple as that. Or everytime you drop 1kg, you reduce 100kcal.

Then when does it stop?
If you're at 1600 calories , do you still starve yourself and go to 1200 calories to lose more weight? It's not sustainable.
Should read this. They were having 1200 calorie diet and their metabolism dropped by 800 calories a day.

One should not just reduce "calorie in" to lose weight.
The best way is to bump up your "calorie out" so that you can get alot more macro & micro-nutrients for healthy body.
Short answer is to stop being lazy. Exercise more, move more. Stop lying on bed for social media and sit whole day to watch tv/play games. Go for a walk, wash, clean, take stairs instead of elevator, etc.
