Of course it is. As long as the word "betting" of money is involve it is called gambling on whatever you do. I know there are people that would say that it's not but the truth is, it really is.
it is definitely gambling in my opinion, though sports might be easier to win sometimes to be honest
"Sometimes" need to emphasis that because in most cases many fixed bet already around the sports house
so even we think the is just easy to predict but if fixed games happen we will be burning out too.
