Cream can refer to a bunch of different things. It’s also regional. Probably most commonly seen, at least in the US, is coffee cream or “half-and-half” which I believe is named because it’s half milk and half (heavy) cream. They have it at every coffee shop.
Heavy cream and whipping cream are much higher in fat. If you whisk it, you’ll get whipped cream. If you keep going you’ll get butter. If you make yogurt out of it, you’ll get creme fraiche.
Different countries name things differently because dairies are so local and regional and agricultural laws and customs vary. For example, you can get the same products in Canada but they are also tagged with the fat percentage (i.e. milk 3%, half-and-half 18%, whipping cream 35%).
