Your specific example of plagiarism is odd; I'm not sure what's difficult to grasp there. But wide ranging dedication (or professionalism if you prefer to call it that) is pretty standard at brick and mortar universities - it's pretty standard for a subset of people to prefer the partying and socialising aspects, and also pretty standard for quite a lot of people to drop out altogether.
