Thinning or balding at 60?

I have noticed many 60 years old men’s hair start getting thin and become sparse, revealing some of their scalp skin underneath, but is this the same thing as male pattern baldness that a lot of guys having during their 30s to 50s? Those old men have a more sparse hair compared to their younger self but is still not balding like those 40 year old men with male pattern baldness...
