Daily Calorie Needs Question

Hello!

I am a 170 cm tall woman weighing 94 kg.I am walking 10,000 steps daily, including everyday movements like Zumba, cleaning at home, shopping, etc. I am not doing any special workouts besides that.

I lost 9 kg in the first month (mostly water and edema loss) and 5 kg in the second month. Based on the weight I lost in the second month, my daily calorie requirement should be around 2800 calories.

My first question: Since I am not particularly tall and I do not do any specific workout besides 10,000 steps, is it normal that my daily need is 2800 calories? Is there a mistake? How many calories do girls typically consume in a day with a similar routine?

My second question: My goal is to reach 54 kg and continue with 10,000 steps daily. Some websites say I should take around 2000 calories per day for this plan. That seems too much to me. How many calories do girls with similar height and weight usually consume daily?

Thanks!
