Don't buy any bitcoins then you will safe from online gambling.
Bitcoin is not the only currency used in on line gambling. You can also pay with credit/debit cards to do on line gambling.
Does it mean you should decline to be paid with your local currency so that you will not do on line gambling?
having bitcoin integrated makes gambling more accessible though, i would bet that a fair number of people that start gambling online start so with bitcoin instead of fiat currencies. not only are the laws not set in stone for bitcoin, there are less fees, no verification, and no accounts may be needed in most cases.
