This decision doesn't legalize sports betting. It allows the individual States to do so if they wish. DraftKings is (was?) operating under a loophole in Federal law that allows fantasy sports, and had, until now, the advantage of actual betting being illegal while "fantasy sports" were not.
Now that states can allow betting directly, they can do things like require a gaming license to operate, require a physical location, etc. Many may still prohibit online gambling. Federal law that prohibits online gambling can still also prevent straightforward betting over the Internet.
