Car accident settlement

At time of being hit in car accident, I had a 25/50/25 policy w/ UIM 25k , not sure what other driver had but I know they have GEICO. if they have a minimal policy as well, and my lawyer gets that person’s limit which is likely due to severity of accident , that means I can only get 25k from them then 25k from my own UIM if max right? So 50k total even if it’s worth more? I do have a lawyer but I’m waiting to hear back on what type of policy at fault drive has
