My question is can it still be called gambling if it is not played with money?
I won't regard this as gambling because no money is staked. There is completely nothing to lose if the prediction goes wrong so I will just call it a luck trial. Gambling to me involves staking something with the hope that our predictions will give us access to more funds. But as long as nothing is staked and there is nothing to lose and little or no emotion will get involved it is just a way to try out how lucky you can be.
Yes, that's true, there should be what will stand as stake even if it's not a monetary value, this can comes in a form of an item or any valuable to be used as stake, but i will advise not to always result in using other alternative options as stake whenever you're not having money to gamble, many had turn to having less or nothing at the cause of doing this and we should not be too addicted to gambling in such manners.
