Is cricket a game of luck?

Last night i saw a match between India and Sri-lanka. There were many moments which made me think that cricket has lot to do with luck. Some decisions which went in favour of batsman were totally wrong. At one moment the ball struck the wickets and bails did'nt come of. What a luck. Toss has a major role in the cricket. The captain with a strong luck always have the upper hand. Toss is just a matter of luck, i can say that. Am i right in saying that cricket is a game of luck.
