Smart strategies are entirely possible in sports betting; it’s wrong to say that there are no smart strategies in gambling if by gambling we mean sports betting (betting in general). One example of a smart strategy in sports betting is the “value” strategy. It’s based on the “edge of the bookmaker’s line.” Simply put, you analyze the bookmaker’s bets, look for inaccuracies in the odds, and try to play on them. In the long run, this can bring you profit.
In fact, there can be no smart strategies in casino games that are completely based on luck. However, even there, strategies are possible. For example, the Martingale strategy. In general, this strategy is unprofitable, since you are playing a game with a negative mathematical expectation, if we are talking about games like roulette or dice, but sometimes luck can be on your side.
As I do not see smart strategy that can be used to win while gambling with casino games, also I do not see any smart smart strategy that can be used to win bookmakers. The start of someone thinking of making money while betting, that could most likely be the start of increasing the money he wants to be using to bet. The person should not be surprised if he later finds himself losing than expected. I do not see anything as smart strategy. I only see strategies but which people should not think as a smart strategy or a strategy that can be used to make money while gambling.
