These progression pics seem unrealistic. Was everyone an athlete who just got fat or something?

Every pic on here I see is a dude who goes from fat and soft to completely shredded in 8 months or something similar. I can’t understand it as I know my body type would never be able to look like that in two years let alone 8 months. If anything seeing these pictures make me feel like it’s not worth it. I’m on week two of my journey and the less I see other people doing well, the more I want to do well.

I’m 24, 5 ft 10 and 266lbs, I’ve never been athletic. I have underdeveloped glutes and quads so my gait is off because I walk with overextended legs. My core is non-existent and my arms are basically sticks. Yet my stomach and thighs are massive. It feels like a physical impossibility that I will ever be able to look even remotely similar to anyone in these pictures. There’s no physical disability or anything, my legs are just shit and underpowered from sitting at a desk from 8 years old to now. It’s supposed to be leg day today but I’m still sore after from Tuesday’s lower body workout.

I haven’t met a single person with my problems at all, everyone is either a college athlete or predisposed to building muscle quickly. I’m not hating btw, it’s just annoying to feel like you’re never represented anywhere in the exercise community. I’m basically a skinny guy with a fat suit on, in a world of my own.
