Are you referring to Petri ranked #19?

I'd guess the allocations will be similar if not the same to how the recent 64 player WPA Players Championship was done in Vegas in April. From a March post regarding that event, CSI responded:
"Good question. The allocations for the WPA Players Championship are as follows:
WPA rankings (16)
APBU (8)
EPBF (8)
BCA (6)
CPB (4)
AAPA (2)
OPBA (2)
WPA wildcards (2)
Qualifiers (16)
The Stage 1 Qualifiers are the only avenue for a person not invited to get in. Anyone may register for the qualifiers."
One spot was also going to come from the recent US Opens in Vegas:
"The all-around champion will receive a $3,500 bonus plus an invitation into the 64-player, $100,000 added Predator World 10-Ball Championship in July". So from the world 10 Ball site (
https://www.world10ball.com) this appears to have gone to all-around runner up Kiamco.
Will the Diamond Las Vegas Open right before the event also give a qualifying spot?

They should have less qualifiers from that "stage 1" nonsense and just allocate more to the BCA (inc host country) and Asia.
