Without having knowledge on the game and you do betting means, It's not sports betting we call it it's slot games betting. Yup in slot games only we play blind games without thinking anything here the result depends on our luck. Same thing happens if you play betting on without knowing games.
That is still sports betting as that fall to the definition on how games are played, you bet is based on sports. For some gamblers who have a deep knowledge in sports handicapping, they call it as sports investing and that is the opposite of what you are doing. When sports investing, you have a game plan to follow and you need to have a decent bankroll for long term betting.
