I get the current amount that the user has after buying a soldier. Do-while () keeps repeating, even if I enter 50

Hello, I would need help. In the console, I get the current amount that the user has after buying a soldier. Do-while () keeps repeating, even if I enter 50.

do {

do {

 System.out.println("Jaké si vybereš?");//What is your choice?
    System.out.println("Pešák-0(2)"); //Plebs
    System.out.println("Lučištník-1 (5)");//Archer
    System.out.println("Jezdectvo-2 (10)");//Cavalry
   System.out.println("Težká jednotka-3 (20)");//Special unit
   VyberVojaky =  Integer.parseInt(sc.nextLine());//ChooseSoldier

    System.out.println("A kolik jich chceš?");//How many soldiers do you want?
     PocetVojaku = Integer.parseInt(sc.nextLine());//numbofSoldiers
 for(int i=0;i < PocetVojaku;i++) {
     System.out.println(armadaHrace2[VyberVojaky]); //secondPlayersarmy[chooseSoldiers];

 }
    //total amount
    // limit for recruiting soldiers is 50,so if player will recruit more than 50 soldiers,The game should alert the player and select the soldiers again


   }

   celkovyPocet -=  PocetVojaku;//total amount -= numbofSoldiers

   System.out.println("Ještě můžete naverbovat: " +  celkovyPocet + " " + "vojáků");
                      //How many soldiers player can recruit

   Vojaci = armadaHrace2[VyberVojaky];

   Penize -= armadaHrace2[VyberVojaky].getCena();
   //money
   System.out.println("Vybral sis" + armadaHrace2[VyberVojaky]);//Your choice
System.out.println("Zůstalo ti:" + Penize + " " +"peněz");//Your residue

if(CelkovyPocet > 50) {

                 System.out.println("Naverboval jsi více jak 50 vojáků");//You recrutied more than 50 soldiers
                 kontrola = false;
             }
             if(CelkovyPocet < 50) {
                 kontrola = true;
             }
             CelkovyPocet = CelkovyPocet - PocetVojaku;

            }while(kontrola == true);


          //total amount

}while(kontrola == true);

}while(  celkovyPocet != 0  );

System.out.println(armadaHrace2[VyberVojaky]);//second Player's army
