Yes, that’s what attracts most people who wish to receive such a bonus. That does not come as granted, though, as you can’t simply take the bonus money & withdraw it right away. As the money is given to stimulate your playing activity on this or that gambling house, then you can use it initially only to make bets & it is credited to the ‘bonus’ account, not the main one, which will be replenished as you deposit real money.
