Yes, it's such a strangled conversation because it's hard for her to say anything and there's so many things it could mean. Is she thinking about how she didn't have the luxury of making mistakes? That Paige is no where near at the level she should be at by now? That she thinks she's going to die soon and Paige won't be ready? Is it just automatic pride in herself? The central message seems like it has to be about Paige's general non-readiness.
