Is it possible there are no coincidences?

In my opinion, the word luck is just a four letter word and it doesn't invovle a person with some chance on there side to get good things or for good things to happen to them. The two words that come to mind when i think of luck are Miracles and Chance. They are two completely different things. Chance can be used in an example to deal with gambling. Theres a possible that you may win or lose. Sometimes, people have enough chance to win a lot of games (that invovle money.) What is the mean of the word luck/chance? Luck/chance is something we take advantage of. It's something that gives us advantages and helps us accomplish things in life. For example, if you're a gambler, and you tend to gamble a lot, you either win a lot of cash, or lose miserably. You might lose so much that you would want to commit suicide because you can't pay off your debts anymore. Miracles are something totally different. An example would be, a man couldn't be seen because he lost his one eye in a fight with a mnokey, but one day he could see everything again. Miracles can trick us at sometimes. When we watch how these guys say they we're sent to earth by God. On top of that you see all these people with sicknesses becoming cured. Even tho there is no way those are miracles but basically Coincidences.
