What is the difference between the single-year and career-long lists?

The single-year list ranks scientists on the citations their work received in one year. The career-long list ranks them on citations across their whole career. Both lists are published every year, and a scientist can be on one, both or neither.

What is the official source of this data?

The rankings come from the science-wide author databases of standardized citation indicators published by Ioannidis et al. in the Elsevier Data Repository, updated every year. TOPSCINET, an independent platform, organises that data by country, year, institute and field, so you can compare and explore it.
