Your heart rate at under 80 is NORMAL. When you exercise it will increase, and the younger and fitter you are the more it can increase. Personally I dont think 190 as a maximum is that high - maybe you werent really trying
Many athletes can get over 200 although people who dont exercise and are less fit will not.
We dont have averages nor standard deviations for heart rates I am afraid. Too much normal variation. There are many reasons for a fast resting heart rate including atrial fibrillation and heart failure, which are not healthy and would not get a Class 1, and anxiety which is common and should do
You seem on the evidence provided within normal limits
