umm... yes you must deposit something to cash this out according to their terms...
$10 free money sign up offer
This offer may only be redeemed once per person.
When a player opens their first Royal Vegas Poker account, they will receive $10 in their account within 24 hours.
Prior to withdrawing any amount of this bonus, the player must play in a minimum of 10 raked hands per $1 of the total bonus, at tables with limits no lower than $0.25/$0.50.
The player must have made at least one deposit at Royal Vegas Poker.
