48% of the ticket revenue is shared to the central pool. The Twins are a below average revenue team so they receive more than they put in. Each additional dollar that comes in gets offset by the Twins getting less money from the central pool.
Let's make the math easy - Twins get $100M, they share $48M and keep $52M. They're slightly below average revenue so let's say they get $52M back from the pool. That gives them $104M in revenue.
Now let's say they have a winning season and make $110M, they share $53M, keep $57M but still only get $52M back from the central pool because their extra $5M in pooled revenue is offset by someone else's drop of $5M (someone wins and someone else loses every year). That gives them $109M in revenue. Each additional dollar only nets them 50 cents.
Here's the real drag - now the Twins are a net contributor to the pool so they don't get the perks that come with being a revenue sharing recipient - draft pick compensation for Sonny Gray is not as good, they lose a higher draft pick if they sign a free agent who rejected a QO and they can't be in the draft lottery in 2024 because they moved up in the draft in 2023. They could also move from Competitive balance round A to round B.
