Can online casinos really boost local economies?

I’ve been reading up on how online casinos contribute to local economies by creating jobs, generating tax revenue, and even funding community projects. But I wonder, how impactful is this in regions where brick-and-mortar casinos are already dominant? Do online casinos truly offer unique economic advantages, or are they just siphoning players from physical venues? Would love to hear insights, especially if anyone has data or personal experiences related to this!
