Does this mean I'm actually pretty?

I'm a bit on the chubby side for my height, but I think my face is decent despite my weight. My friends tell me I'm an 'unscratched lottery ticket' and that I'd look insane if I just lost some weight. Another friend says I carry my weight well while she looks like a mess when she gains weight, and even the teachers say I'm on the prettier side. Even the guys say I just need to slim down... is it for real? I'm thinking of actually trying to lose weight now.
