No, it doesn't happen all the time. But it would be the most exciting thing to happen in an NBA playoff series or even the finals. It only happened 84 times in the history of the NBA where a playoff series or finals reached game 7.
Ever since the mid-1980s, all playoff series of the Stanley Cup are decided in best-of-seven games.
Every team that started a World Series 3-0 has gone on to win that Series. Indeed, in major league baseball, only one team -- the 2004 Boston Red Sox, in the ALCS -- has come back from losing the first three games in a seven game series and forced a game seven (they won that game over the New York Yankees).
There are actually only 7 teams in the NBA who rallied from 3-1 to win a playoff series. They are the Boston Celtics (1968), Los Angeles Lakers (1970), Washington Bullets (1979), Boston Celtics (1981), Houston Rockets (1995), Miami Heat (1997), Detroit Pistons (2003) and the Phoenix Suns (2006). So Mathematically only 23.33% of all NBA teams won an NBA playoff trailing from 3-1.
The NHL playoff schedule works similarly every year. There are sixteen teams that make the playoffs and these face off in best of seven series until only eight teams remain.
The current system arose in 2007 after some controversy when it was shown that in the previous system, division winners were seeded higher than any other playoff participants, regardless of their record. A detailed history of the NBA playoff system is linked below.
The NBA playoffs are played "best out of seven". For instance, the Celtics may win the first three games of the playoffs, but if the Lakers win the fourth game, the playoff continues until the Celtics win another game or unless the Lakers win the final three. There will be seven games max and four games minimum.
The baseball playoff competitions are structured so the team that advances and wins the World Series must win 11 games. The breakdown is as follows: American/National League Division Series - Best 3 of 5 games American/National League Championship Series - Best 4 of 7 games World Series - Best 4 of 7 games.
