Confusion About RLWL/7 to CNF/0 Ticket Status

I am a bit confused about my ticket. When I booked it, it was available for chair car, but after booking, the status is RLWL/7, and current status is CNF/0. What does this mean? I haven't been assigned a seat number. Does this mean my ticket is confirmed but I might not have a seat? Should I ask the TC where to sit? Can I still travel on this train?
