FIRST of all
you missed FOCUS on the subject, or more specifically your D500's AutoFocus system gained focus, but maybe the camera was set for Manual Focus ?
If you look at the grass in the background you'll see the ground is IN FOCUS. Even though your FOCUS POINT is on the subject
So I would go back and learn how to focus properly with the D500. The EXIF states you were focusing in "Manual" instead of using the AutoFocus??
I think you had the camera in MANUAL Focus, and not AutoFocus or something else was not set right ??
Check the little lever on the left front bottom of the camera. It could be set to "M" instead of "AF". AF is AutoFocus, M is Manual. If in M the lens will *not* AutoFocus.
Also check the Lens to make sure it did not have a switch to M instead of AF.

But another generally issue with sports, the issue you'll get is your Shutter Speed of 1/6th of a second.
For sports you'll probably have to be up to 1/1,000 to 1/2,000th Shutter Speed depending upon the size and speed of the players to *stop* motion and prevent blurry images. Quite a BIG difference from your 1/6.
That is way TOO SLOW for any type of movement.
To Compensate you Have to RAISE your ISO way above ISO 100.
By raising your ISO, you'll be able to raise your Shutter Speed.
You should be good up toe 51,200 ISO with the D500
I shoot with a D500 DX and D750 FX cameras.
In lower light with the D500 you'll be better served by setting ISO to "AUTO ISO" - press the ISO button and rotate the front dial and it will go into AUTO ISO.
But you'll have to go in the menu and set a MAXIMUM ISO, say 51,200. Then in Manual (or Shutter Priority) set Shutter Speed to a minimum of what you think will work to stop action depending upon the speed of the action. Then ISO will adjust accordingly as long as it's within the parameters of the environment.

But as mentioned the Shutter Speed will STOP motion which you'll have to do irregardless of the amount of light available.
The ISO will help assist in compensating for lower LIGHT, so ISO has to be much higher to assist in higher Shutter Speeds.
If the shutter speed is too SLOW you'll get blurry photos due to movement of the subject and/or the person holding the camera. Most people CANNOT hold a camera steady enough at anything below 1/80th of a second which in itself can cause blurry images even on a static subject such as a building, which probably isn't moving.
