That's the clause in the agreement they use to justify the increase in rates, but it's unclear it's actually "risky" when it's a large company like Valve.

The risk is not from Valve; disputes pass through to the processor. This is the same problem dating sites, gambling, etc. all deal with. Any sufficiently large adult oriented business becomes a de-facto payment processor, where their entire core business function is in managing this risk, not whatever they actually do for the end user. It's either that, or charge the exorbitant fees that come with using a niche provider who takes on that risk.
