You could use the slice pipe.

<li *ngFor="#user of users | slice:1">
  {{ user.name }} is {{ user.age }} years old.
</li>

The first parameter corresponds to a positive integer representing the start index.

There is the SlicePipe for this use case:

  <li *ngFor="let user of users | slice:1">
    {{ user.name }} is {{ user.age }} years old.
  </li>
