The provided web search results mention the SARB noting data in its quarterly Bulletin, but none of the snippets specifically confirm that the SARB 'delivered an important corrective to one of the most potent claims driving the country’s current regulatory debate around online gambling' in its bulletin 'two weeks ago.' The evidence is general regarding SARB's commentary on gambling but lacks the specific confirmation of the 'corrective' mentioned in the claim.

The evidence provides general definitions for GGR (Gross Gaming Revenue) as the difference between amount wagered and amount won, and mentions wagering turnover, but none of the sources contain the specific quantitative breakdown (90% to 97% returned, GGR is a fraction) required to verify this claim.

While the web search results discuss money leaking offshore and the lack of tax contribution from illegal activity, they do not provide multiple independent sources confirming that the money *leaks* and specifically *fails* to contribute to the tax system, responsible gambling programs, and local communities simultaneously. The evidence is suggestive but not fully corroborated across multiple distinct sources.
