Gambling, that means invest in yourself and your luck. There is games for every taste, and different skill. If you ask me I suggest poker, you have enough to try many times some tournament with great payout. Other is investing in casino bankroll, that means you are investing in other people to lose, you bet against their (our) luck.
Both ways are good and risky, with risk you can count on high profit, or great loss. What ever you choose my friend I wish you luck. I don't think you can find safer investment, so hurry and don't miss your train now when you have good money for start.
Poker is only an option if OP is already a seasoned player that has been able to pull out winnings in a consistent fashion, if this is not the case then it should be out of the question.
