But since probably 100x times as many kids play basketball or football than box, your odds are probably similar.
Also, I'd counter-intuitively bet that careers in boxing (when found) are longer lasting than in pro football. Pro football players get very moderate money for what tends to be extremely short careers that leave a lot of damage. My grandfather couldn't walk for the last 10 years of his life from football damage to his knees he picked up 60 years before.
My only issue with this is that Boxing isn't as dominate of a combat sport as it once was. MMA/UFC has split the market share and by most accounts is more popular than Boxing. This reduces the total number of professional boxers that actually "make it" since most paid boxers rarely get a fight card that is worth significant cash.
But if you combine MMA/UFC with Boxing I would bet you're math is reasonable.
True. Olympic medallist Tony Jeffries made a video about this a couple of days ago[1]. Even if you become pro, chances are you won't be making any significant money.
