I want to gain muscle but without losing weight.

I hope I can explain this right but at the moment I weigh about 56kgs and I’m 6ft1 (21 years old). My TDEE is about 1900 calories so I’ve been working really hard on being in a calorie surplus every day. I’m currently eating approximately 2500 calories a day. I’m going to start going to the gym but I dont want to burn more calories than my surplus so that I just loose weight (if that makes sense). I’m really new to this so correct me if I’m wrong please but if I did a workout and burnt 1000 calories after eating 2500 calories in that day would that just cancel out my surplus and make me loose weight? Or do I just need to make sure I don’t burn more than my surplus? Thanks in advance for any advice.
