Min value = 0 always on statistic sensor

I have a sensor that has my cell phone data total for the month in the past 12hrs but when I put the sensor in a statistical sensor, it always shows 0 as the min value when it should be greater than 500.

    sensors:
      celldata:
        entity_id: sensor.fido_111111_data_used
        value_template: "{{  (states('sensor.fido_11111_data_used') | int / 1000 )  | int  }}"
        unit_of_measurement: 'Mb'
        icon_template: "{% if (states('sensor.fido_1111_data_used') | int / 1000 ) > 100 %}mdi:square-inc-cash{% else %}mdi:download{% endif %}"
