potty training wasn’t needed?

hi this might be a weird post but my puppy has been with us for 3 days since day one she never peed inside her crate and KNOWS to go outside in our backyard. we’ve even taken her out on car rides, no accidents and waits till we take her to the backyard for her to pee. i’ve only had 2 accidents inside the house because we didn’t take her out to pee ASAP when she finished eating/drinking water. shes an australian shepherd im just curious if this might only last for a few days or when will i truly know she is potty trained. i honestly dont even give her room or time to sniff around the house after she eats and take her out immediately. i have a lot of time right now to really look after her with a close eye but idk if im actually training her or no?

thanks !
