What's wrong? I'm confused

I do not understand what are you asking. In last video the only way you taught was by using "if/else".

ScrabblePlayer.java 
public class ScrabblePlayer {
  // A String representing all of the tiles that this player has
  private String tiles;

  public ScrabblePlayer() {
    tiles = "";
  }

  public String getTiles() {
    return tiles;
  }

  public void addTile(char tile) {
    tiles += tile;

  }

  public boolean hasTile(char tile) {
   boolean win = tiles.indexOf(tile) != -1; 
    return true;

   boolean win1 = tiles.indexOf(tile) != -1; 
    return false;



  }

}

The expression tiles.indexOf(tile) != -1 returns a boolean, it is true if the tile is in tiles and false if not. That is also the exact same thing the method is meant to return.

If you use an if statement you are essentially saying "if this expression is true return true, if it is false return false" which is clearly a redundant thing to do.

The efficient solution and the one the task is looking for is to return the expression directly like this:

public boolean hasTile(char tile) {
   return tiles.indexOf(tile) != -1; 
}
