To offer a different perspective, becoming a D1 college football player or basketball player is much more difficult than walking on to a D1 rowing team, and I really don't mean any offense by that. I know a few rowers at my school and that process does seem like hell.
With football, at least last year, there were ~1 million high school football players (

If we assume that it's equally distributed by grade, then there are about ~250,000 football players (and this is an overestimate, seeing as a majority of players will join as freshmen with some who will eventually quit before their senior year).
To become a D1 football player, generally, you need to be in the top 2,000 players to be even CONSIDERED for D1 football (aka Top 0.8% of high school football players in your class). To get that recognition is a whole other deal for high school football players. It's constant camping, recruiting visits, traveling, working out, etc. to get recognition from other schools to be considered for a scholarship as a part of their class. Not that other students don't go through a lot in high school to get where they are, but the difficulty of becoming a D1 football athlete (especially at a reputable institution) is absolutely insane.
We can repeat this with basketball as well. Last year there were ~540,000 male high school basketball players (

If we assume equal distribution (which again is overestimating), then there are ~135,000 male high school seniors.
Basketball is even more tough with how small teams are (each D1 team has 13 scholarships total (Fr-Sr), so they only take very small classes every year). Typically, top ~1,000 high school basketball players are considered (~Top 0.7%) for D1. Same deal with football. To get there involves constant camping, etc. to be at the peak of their game.
When people say "ball is life", for these athletes who make it to D1 football/basketball, it literally is their entire life. Like it's not just a stroke of luck for a majority of athletes (especially basketball) to make it to D1.
At least to me, that's why D1 football/basketball players are held up in such a higher light: the process of becoming one is absolutely insane relative to anything else I've seen.
