Dr. Jaiwant Rangi uses an empty tank analogy to explain insulin deficiency versus resistance. Diabetes isn't binary but a spectrum from type 1 (no insulin) to varying degrees of resistance, with many patients showing both. Where you fall on that spectrum determines your treatment.

No amount of pushing the gas will help. If you treat an empty tank like stuck brake, you fail and you lose the precious time. And that's exactly what was going on with Dorothy. She was not making enough insulin and she needed help with that. So she had insulin deficiency. So in most people, what we understand is they may have completely one way or the other. They may have complete resistance of insulin where they're not responding, or they have complete deficiency, which is in extreme cases we are calling that type 1 diabetes. And there could be a spectrum in between where they may have some deficiency, some resistance, or they may have more resistance, less deficiency.
