You can read a Wikidata item about a particular person and learn key bits of information about them, but as a human (Q5) it's usually easier to access and piece together that information from a Wikipedia article. There are tools that make Wikidata items easier to interpret (Reasonator and SQID are some tools that Wikidata's information easier to read), but the power of Wikidata doesn't come from reading entries. The real power of Wikidata comes from queries.

In this training module we'll explore the world of Wikidata queries.
