It depends on the R:R of the trades you take.
You can have a terrible strike rate but if you have excellent risk management and take only high R:R set ups, you will still be profitable.
Conversely, if you have a very high strike rate but take poor R:R sets up and risk too much capital per trade, you will always lose money. It's okay to have a lot of losses. Keep the losses very small, let your winners run and see the difference.
