Solved Inventory Gui

Ok so i made a inventory gui that opens up players stats, etc.
But lets say if i open mine up and see my stats and while another player open his up it will change mine to his.

how can i fix this problem?
Code:

Code:

    @SuppressWarnings("deprecation")
    @EventHandler
    public void playerInteract(PlayerInteractEvent event){
        Player player = event.getPlayer();
        Action action = event.getAction();
        ItemStack is = event.getItem();
        if(action.equals(Action.PHYSICAL) || is == null || is.getType() == Material.AIR)
            return;
        if(player.getInventory().getItemInHand().getItemMeta().equals(items.PS.getItemMeta())){
            openPS(player);
        }
    }

    public void openPS(Player player){

        playerStats.setItem(20, items.TLGSTATS);

        playerStats.setItem(49, items.B);

        player.openInventory(playerStats);
    }

    public void openTLGSTATS(Player player){
        ItemStack kills = new ItemStack(Material.SKULL_ITEM, 1, (short)3);
        ItemMeta meta = kills.getItemMeta();
        meta.setDisplayName("§7Kills: §6" + playerstats.getKill(player));
        kills.setItemMeta(meta);

        ItemStack deaths = new ItemStack(Material.SKULL_ITEM, 1, (short)2);
        ItemMeta meta_deaths = deaths.getItemMeta();
        meta_deaths.setDisplayName("§7Deaths: §6" + getDeath(player));
        deaths.setItemMeta(meta_deaths);

        ItemStack wins = new ItemStack(Material.BANNER, 1, (short)1);
        ItemMeta wins_meta = wins.getItemMeta();
        wins_meta.setDisplayName("§7Wins: §6" + getWins(player));
        wins.setItemMeta(wins_meta);

        ItemStack loss = new ItemStack(Material.BANNER, 1, (short)15);
        ItemMeta loss_meta = loss.getItemMeta();
        loss_meta.setDisplayName("§7Losses: §6" + getLosses(player));
        loss.setItemMeta(loss_meta);

        double kdamount = getKill(player);
        if(getDeath(player) > 0){
            kdamount = (double) getKill(player) / (double) getDeath(player);
        }

        ItemStack kd = new ItemStack(Material.SKULL_ITEM, 1, (short)0);
        ItemMeta meta_kd = kd.getItemMeta();
        meta_kd.setDisplayName("§7KD: §6" + kdamount);
        kd.setItemMeta(meta_kd);

        TLGStats.setItem(11, kills);
        TLGStats.setItem(13, deaths);
        TLGStats.setItem(15, kd);
        TLGStats.setItem(30, wins);
        TLGStats.setItem(32, loss);
        TLGStats.setItem(49, items.B);

        player.openInventory(TLGStats);

@EventHandlerpublic void invEvent(InventoryClickEvent event){
Player player = (Player) event.getWhoClicked();
ItemStack clicked = event.getCurrentItem();
Inventory inventory = event.getInventory();
 if(clicked != null && clicked.getType() != Material.AIR) {
if (inventory.getName().equalsIgnoreCase(playerStats.getName())) {
event.setCancelled(true); 
if (clicked.getType().equals(items.TLGSTATS.getType())) {
openTLGSTATS(player);
event.setCancelled(true);
}
if (clicked.getType().equals(items.B.getType())) {
event.setCancelled(true);
player.closeInventory();
}
}
if (inventory.getName().equalsIgnoreCase(TLGStats.getName())) {
event.setCancelled(true); 
if (clicked.getType().equals(items.B.getType())) {
event.setCancelled(true);
openPS(player);}
}
}



    }
