No it's not like that. kawbet blocks accounts if a player wins too much money. A well-known trick of 1xbit is that there will be a message that you cannot request a payout. The message "Account is checked by security department" appears.
They just leave your money, so you can continue to gamble until it runs out. And if you don't gamble, the department deliberately does nothing so that you can never pay again.
In the best case for the user, you will receive your deposit back, the rest would have been won unlawfully.
The company behind this is BETB2B and because it is Whitelabel, it is handled by Kawbet and BETB2B. If one of the two parties does not want to pay, you are the hare and you have lost everything.
Of course BETB2B is not coorporating because this company gets about 35% from the profits from Kawbet!
So we have both Kawbet and BETB2B who are not going to approve the payments for you.
Outright SCAM, 1xbit works exactly the same. Kawbet borrows this platform from betb2b and determines whether they pay or not.
But so far only accounts are blocked. They are thieves.

I want to warn everyone about Kawbet, don't go here. Outright scam
