It didnt say battery size anywhere, because tesla does not quote that, but no, a model 3 standard does not have that battery size. I believe there is a discussion in the UK and Ireland subforum on the battery size (which is in the 50s for the standard NCA battery and I have no idea for the LFP battery that you will get now on a standard model 3.
Although they have yet to update their website, Tesla has quietly increased the size of the battery pack in the Standard Range Plus (SR+) Model 3 made at Giga Shanghai. More info here: DriveTeslaCanada
