Also, what language do i should go for first.
Also a roadmap from beginner to pro would be of great help

Answer 1

To be a pentester (a good one). You need to be well versed in multiple programming languages, front/back end and also be very familiar with network topologies, equipment, protocols, and how said protocols work.
Not discouraging you, but you got your work cut out for ya
