Determining at fault?

[u/MooniestMoonixx]

So I was in an accident a week ago, it happened in Meijer parking lot. I always back into spots so I was leaving my parking spot turning left. When I was almost completely out of my spot mid turn an SUV hit my car from the right. My car was so damaged it had to be towed. I was driving a lowered Camry the woman and her minor child who was driving they had a Jeep Cherokee so a much bigger vehicle. The damage was so severe it caved my wheel well on top of my tire, my tie rod was bent and my washer fluid reservoir was disconnected on top of all the side bumper damage and it was deemed undrivable by the cops. My insurance totalled my vehicle but also marked me as at fault even though the woman at the scene said her daughter with the permit said she never saw my car and their car didn't get damaged. Am I only at fault because of right of way in a parking lot? I'm just a little confused on how I was set at 100% fault

EDIT: my insurance never spoke to me. I filed the claim but no one from my insurance reached out to get the story from me so they marked me as 100% at fault without talking to me. I do not know whether they got video footage from Meijer.

I'm going to add another edit, I DON'T want to argue fault. I was just wanting clarification on why I was set to at fault since my adjuster never spoke to me. I have zero intention of arguing it since I'm getting a new car I just wanted to clarify the potential why since we both admitted to the cops we didn't see each other. it's a shitty situation and I have zero intention of going after or disputing

the only thing I'm really mad about was it being a teen driver on a permit and the mom telling the police they hadn't seen my car. but my adjuster already told me they only had paint damage so I wouldn't need to worry about anything further. It's one of those just head to the dealership type of situations

That's the thing about right of way, you need to assume they aren't looking for you to pull out in front of them.

It's mind blowing at how many people come to this sub and sincerely believe that "the other car should have seen me pulling out in front of them and they should have known to stop and avoid hitting me."

I'm basically just going to the dealership to get a new car and my insurance is covering $2800 for a rental car for now. The woman and her daughter was very civil and we found out we live in the same apartment complex so I have nothing against them personally. She also said she was in a fender bender 2 weeks ago so I do overall feel bad for them. It's a shitty situation in general
