Ranking System - Like in Rainbow Six Siege + API

Hello Guys. I wanted an Ranking System like in Rainbow Six Siege, but I didnt found one, so I decided to code an system like in R6. I hope you like my plugin and enjoy it. If you found some bugs / errors let me know it.

package at.sciencecode.rsm.ranking; 

import java.util.ArrayList; 

import org.bukkit.entity.Player; 

import at.sciencecode.rsm.manager.FileManager; 

public class RankAPI { 
  
    // ArrayList to see if player is InGame 
  
    public static ArrayList<Player> ingame = new ArrayList<>(); 

    // Get Rank as String 
  
    public static String getRank(Player p) { 
        FileManager filemanager = new FileManager(); 
        int points = filemanager.yml.getInt(p.getUniqueId().toString()); 
      
        String rank = convertPointsToRank(points); 
        return rank; 
    } 
  
    // Get Points 
  
    public static int getPoints(Player p) { 
        FileManager filemanager = new FileManager(); 
        int points = filemanager.yml.getInt(p.getUniqueId().toString()); 
        return points; 
    } 
  
    // Converts the points to a rank 
  
    public static String convertPointsToRank(int points) { 
        if (points < 50) { 
            return "Copper IV"; 
        } 
        else if (points < 100 && points > 49) { 
            return "Copper III"; 
        } 
        else if (points < 150 && points > 99) { 
            return "Copper II"; 
        } 
        else if (points < 200 && points > 149) { 
            return "Copper I"; 
        } 
        else if (points < 250 && points > 199) {
