It is best to review the service ratings before conducting full KYC verification, as negative ratings usually indicate scam and completing KYC will not solve the problem.
Anyway, 148k confiscated is a huge number, and all that with only 3 bets. You should show a little bit more though, betting history, deposit history, chat/email history with the site.
I think it is 148 USDT not 148.915 USDT
I don't think so. Who would post 3 digits after 1$? I am very convinced we are talking about 148k in here. Maybe you are right and OP is so broke he depends on the 0.915$ tho0ugh, who knows.

But whatever it is, 148 or 148k, a sketchy site would keep whatever amount is left.
