Looks like a nice park! Was a bit odd of a read to me because the vast majority of the parks in my part the US are like this (sports fields, playgrounds, lakes, open green space, bike paths, grills, pavilions, etc), didn't realize I had taken that for granted.

I think it varies. "Park" can mean anything from basically wild forest to maintained green space and it may or may not include ammenities such as you listed.
