Can I be on a calorie deficit and lose weight while eating ghar ka khana ?

I'm a newbie who recently started a weight loss journey , and I am planning to join the gym this month. My primary goal is to reduce weight while at the same time increasing muscle. Is it possible to be on a calorie deficit by eating whatever my mother makes ? For various reasons , I am not able to make meals right now , it will take a few months before I start making meals for myself. Should I be aware of anything ? I'm really sorry if this question has been asked before but I'm a bit lost. Any help would be appreciated.
