According to google, ya have just as much a chance with steel rod or carbon :
For all practical purposes, there is no meaningful difference in the chance of being hit by lightning while holding a carbon rod versus a steel rod. The conductivity of the rod is a minor factor in the final path of a lightning strike. The dominant factors are height, shape, and isolation.
Why conductivity is not the deciding factor
Lightning is an electrical discharge miles long, originating from a cloud tens of thousands of feet high. The final path of the leader stroke to the ground is determined by which object or point on the ground first sends up a positive electrical discharge to connect with it.
While steel is a far superior electrical conductor than carbon fiber, this difference is insignificant compared to the properties of the air and the sheer magnitude of the lightning bolt. Both carbon and steel are far more conductive than a person and will increase the overall chance of being struck compared to having no rod at all, but the difference between the two is negligible
