Good movie plot, perhaps, and some (relatively) ethical old-school brick and mortar sportsbooks work that way but the non-market online gambling apps have an established system that they all follow.
They all just use 'lazy odds' compiled algorithmically by outside third-parties like Sportradar, Kambi, Genius Sports, etc and if you show any true ability to beat these odds you just get instantly restricted from betting.
Only losers are welcome to remain on the platforms. Gotta keep things maximally extractive.
