I'm not sure about Kalshi, however on most sports betting sites you actually are betting against the house. The betting sites all have in-house models (or piggyback off other sites) that are much better at predicting odds than the general public. If someone is making money then the sites just place limits on that account so they're not losing money.

It's not too complicated

The average player loses money. Hence the opposite side will make money

Exceptions are dealt accordingly

It comes down to some form of the old adage "the average person thinks they're smarter than the average person". They're not.
