It is really just that there are people who does really love on asking out on something that they do already know. In general then if you arent risking something even not on fiat or physical money form
then it wont really be a gamble. You would really be gambling on something which you do see that you could really be able to benefit into it and this is the time we would really be risking on something
whether it would really be completely lost or would really be getting on the thing that you do want but everything would really be depending or basing up on your luck.
I think everyone doesn't ask something they know unless they haven't found the right answer to that question or the question is multi-definition according to their own perspective. He cites the key word "betting" so one has doubts about whether betting without money is also gambling but the definition of gambling is clear that without betting money or anything physical it is not gambling.
I have never registered on the site that OP shared, but I have reviewed that predictor game betting for entertainment purposes and competitive play win games based on luck, options can also generate high winnings of up to 1 million naira without betting money and we may try it to hunt for luck.
