Table to show the required win rate with each risk to reward scenario for breakeven.
As you can see there is no need for you to be right more often than you are wrong . If you setup your trades or gambles in such a way that if you are right you gain twice as much as you would lose(in case u r wrong ) you would still make money and you would only need to be right only about 33 % of the time to breakeven.
So it essentially shows us one thing we dont need to predict the future even with 50 % accuracy,by confining ourselfs to only those trades/wagers that have reasonable probability and high risk to reward ratios we can make money.
Most traders overlook this simple fact and focus on being right rather than making money ,also they tend to over trade and hence would inevitably lead to load of their capital.
Happy trading and remember discipline is the key☺️
