Larian "ruined" her with her Background. In EA "Urchin" worked with her "Miss Agent 007" backstory. Charlatan would had worked as well (or even better). Making her an Acolyte was IMO a bad move.
Acolyte makes perfect sense for her. She likely was devout before becoming Sharran (Given the religious connotations of what was occuring during her flashback) and still was afterwards.
Charlatan would make zero sense, given that unlike normal Sharran, she is not particularly prone to deception or persuasive techniques (I mean, she spills the beans about being Sharran when you just ask her what's wrong... That's as decidedly non-deceptive as you can get)
Urchin also doesn't make too much sense. She wasn't living on the street. She was with her family in their religious temple and then she lived with the Sharrans in their religious temple.
She was kidnaped as a pre-teen - her stats are due to whatever training she got at the local Sharran Shaolin&Jedi Temple.
To a point. A characters stats are partially shaped by their genetics not just their experiences.
This would be even more prominent for Origin characters/PC's due to the effects of the tadpole causing a reset of power (Hence why people like Karlach and Wyll who have lore that they were excellent and skilled fighters suddenly struggling to 1v1 a worthless goblin) whereby training they received and powers they were given are dulled and their natural genetics will be the basis for much of their starting stats (But with influences from other sources still being there, just not as prominent as it might have been at their pre-tadpole powers)
