In the UK, gambling winnings are not considered income. Asian Connect I do not believe has a UK gambling license, but you will face no penalty for gambling with them if you are in the UK.

Banks in the UK can ask for proof of income, but seldom do. Are you trying to open an HSBC Premier account and show earnings over 100k?

A better way to get this account is to open an HSBC Advance account, deposit 50k in it, or in a savings account or ISA, then apply for a Premier account. You are eligible for a Premier account if you have 50k worth of money deposited with HSBC across all its products. This should allow you to opern a Premier account without having proof of a 100k income, which I assume you do not have as an Advanced account is less likely to ask for proof of income.

This all assumes you legally reside in the UK and can prove this, and better still are on electoral register.
