No, I have never heard of him I guess you could tell us more about him and what makes you think he is a good tipster. From all indications the guy on the video is a fan of Warriors or he is just some kind of guy trying to get the attention of people so that they will either subscribe to his channels or make payments for him to give them games to gamble on. You should always verify the information you come across first before bringing it to the forum so that some people will not get scammed after seeing it here.
