what i tried to figure out is whether "athletes" low resting pulse could be indicator of a "good fitness?" in some cases, or if your resting pulse drops below lets say 70 beats per minute, it will always indicate suboptimal metabolism.Rather than focus on pulse rate, measure and track your HRV (heart rate variability). This is the amount of time between beats. Generally speaking, a healthier heart has more variability between beats than an unhealthy heart. As the variability shrinks and your heart beats more monotonically, that is a classic sign of stress.
Here's a good set of blog posts on the topic from a researcher (who has a financial interest via products he sells, whatev).

I wear an Oura ring and track my HRV. When I drink alcohol, the HRV moves towards 0 (no variability). When I'm healthy, it moves up. However, the topic is more nuanced than that. There's a healthy range for each individual, so tracking your own range and how you move through that range over time is pretty interesting.
It "could be" an indicator of good fitness. But using a single variable like pulse rate isn't a great idea. There could be other reasons for the low pulse rate which are related to an illness.what i tried to figure out is whether "athletes" low resting pulse could be indicator of a "good fitness?" in some cases, or if your resting pulse drops below lets say 70 beats per minute, it will always indicate suboptimal metabolism.

In an athlete, it's likely indicating good fitness. But in the general population, it's a terrible indicator.
You need a few indicators that, when aggregated, indicate good fitness. I'd suggest:
* Low resting pulse rate
* HBR (heart beat recovery) of 20-30 beats per minute (this is the rate at which your heart rate returns to normal after strenuous exercise)
* Stable HRV between 25 and 55 milliseconds
* Stable blood pressure, but 100-125 systolic with 60-80 diastolic
* Stable body temperature between 98F and 99F
