102. Players
In short
A short definitions chapter: who counts as a "player", the "active player" (whose turn it is), "nonactive player", and what phrases like "an opponent" mean. Vocabulary you need for every other chapter.
Informal summary — the official English text below is authoritative.
102.1.A player is one of the people in the game. The active player is the player whose turn it is. The other players are nonactive players.
102.2.In a two-player game, a player’s opponent is the other player.
102.3.In a multiplayer game between teams, a player’s teammates are the other players on their team, and the player’s opponents are all players not on their team.
102.4.A spell or ability may use the term “your team” as shorthand for “you and/or your teammates.” In a game that isn’t a multiplayer game between teams, “your team” means the same thing as “you.”
