Exactly!!! But without more input from the OP we are just speculating...

If you can supply your own light via a flash (not a built-in) in the particular shooting environment, then that gives you all sorts of options, but if a flash is not allowed, then you resort to fast lenses (which limits DOF when shot at wide apertures) and large(r) formats which produce less noise at high ISOs.

Use a tripod and decrease the ISO setting which will increase the shutter time and/or also increase the F stop to the maximum opening of the lens. Depending on the lens, increasing the F stop may cause some softness in the image. Go with decreasing the ISO and increasing shutter time.

But what if the subjects are moving?

Then go to higher ISO to freeze the motion and edit on the computer to reduce as much noise as possible.

Exactly my point. You can’t fix low light with a tripod, slow shutter and IS with moving subjects.

And as we both know shooting indoors sports is a challenge with great gear at times without the advantage of flash.

👍👍 indeed!

That all depends on the situation - if you can use neither bounce nor lots of units, square-distance rule guarantees that things ‘too close’ will be badly over-exposed, ‘too far’ will be very dark, and likely there will be harsh shadows.
You can have lovely exposures with flash, no matter how close you are!

There is nothing wrong with flash, as long as you learn how to use it.

There are some lighting condition that can possibly be lighted with flashes but I certainly can't afford it nor I can do it by myself.

My statement was that if you have a single flash unit which directly lights subjects at seriously different distances, some will be over exposed or some will be under exposed {or both}. That is a direct result of physics.

If you know how to use them, you can get great results at seriously different distances and none would be over, nor under exposed!

I won’t argue the physics further. I do love ambient light, though.
