I don't think you will have an answer to the question. You know that gambling is not the kind of betting you will do 100% of the time. However, most people lose in gambling multiple times before starting to win at the beginning. Since they will be new and they may be playing it without applying any strategy, are you going to count this in another way? Also, because I believe while you are looking at how perfect you are, you need to consider this too, which you won’t do; however, gambling is a probability something you are not sure of and you won’t know the outcome of it, so how do you think you will be able to win? Till you wait for the outcome of the games you predict. Although you can do that based on how favorable it is for you or the type of strategy you use when gambling, it is still difficult for you to know this because gambling is luck.
It will be hard for a gambler to win 1–5 tickets without losing a single game. However, before considering winning 1–5 tickets and be claiming experience or a good gambler, you also need to check how many games you lose before you win those 5 tickets that make you an experienced gambler. However, you are right by saying his percentage will drop when he continues losing bets, which is constant; there is no magic for that one to lose.
