It's because you've assigned your own ID (playerid), instead it should've been the specified (id) like this:

Код:

CMD:stats(playerid, params[])
{
    if(connected[playerid] == true) return GameTextForPlayer(playerid, "~r~Spawn First", 5000, 5);
    new id;
    if(sscanf(params, "u", id)) return SendClientMessage(, -1, "{c3c3c3}(INFO) /stats [id]");
    SendClientMessage(playerid, -1, "{CECEF6}* You are viewing /stats.");
    new string[900], stats[900],str[129], name[MAX_PLAYER_NAME];
    GetPlayerName(id, name, sizeof(name));
    format(str, sizeof(str), "{4286f4}Player name {FFFFFF}%s {4286f4}database id {FFFFFF}%i\n\n", name, pInfo[id][ID]);
    strcat(stats, str);
    format(string, sizeof(string), "{4286f4}Admin Level:                                       ( {FFFFFF}%i {4286f4})\n", pInfo[id][Admin]);
    strcat(stats, string);
    format(string, sizeof(string), "{4286f4}Score:                                                  ( {FFFFFF}%i {4286f4})\n", pInfo[id][Score]);
    strcat(stats, string);
    format(string, sizeof(string), "{4286f4}Points:                                                 ( {FFFFFF}%i {4286f4})\n", pInfo[id][Points]);
    strcat(stats, string);
    format(string, sizeof(string), "{4286f4}Respect:                                              ( {FFFFFF}%i {4286f4})\n", pInfo[id][Respect]);
    strcat(stats, string);
    format(string, sizeof(string), "{4286f4}Kills:                                                     ( {FFFFFF}%i {4286f4})\n", pInfo[id][Kills]);
    strcat(stats, string);
    format(string, sizeof(string), "{4286f4}Deaths:                                                ( {FFFFFF}%i {4286f4})\n", pInfo[id][Deaths]);
    strcat(stats, string);
    format(string, sizeof(string), "{4286f4}Ratio K/D:                                         ( {FFFFFF}%.2f {4286f4})\n", floatdiv(pInfo[id][Kills], pInfo[id][Deaths]));
    strcat(stats, string);
    ShowPlayerDialog(playerid, 55, DIALOG_STYLE_MSGBOX, "STATS", stats, "Ok", "");
  	return 1;
}

I'd also suggest to check if IsPlayerConnected(id) and return an error message if it's false.
