You are only out if one of these things happens:
1. The bowler ('pitcher' in BB) hits the stumps behind the batsman, this is called being 'bowled out'
2. The ball is caught directly from the batsman's strike ('caught out')
3. The fielders manage to hit the stumps with the ball before the batsman has finished his run ('run out')
4. The batsman blocks a ball that would have hit the stumps with his body instead of his bat (this is called LBW, Leg Before Wicket)
These are the most common ways to be out, there are other ways to be out, but to get back on topic: to compare the six strikes system to Cricket would seem to suggest that you are not 'out' until they have proved your guilt.
