You can try using Array splice

    this.api.getAdminList()
      .subscribe(
        data => {
          if(data.length > 0) {
            this.data= data.splice(0,1);
          }
        });

or try reversing the array and then popping the last item

    this.api.getAdminList()
      .subscribe(
        data => {
          if(data.length > 0) {
            this.data = data.reverse().pop();
          }
        });

getAdmins() {
    this.data = [];
    this.api.getAdminList()
      .subscribe(
        data => {
          this.data = data.shift(); //The shift() command will remove the first element of the array
        }
      );
}

Try:

this.api.getAdminList().pipe()
  .subscribe(
    data => {
      this.data = data.splice(1);
    }
  );

Have you thought about using splice?

this.data = [];
this.api.getAdminList()
  .subscribe(
    data => {
      this.data = data.length > 1 ? data.splice(0, 1) : [];
    }
  );
