There were people who do even bet on other sports without knowing then it is clearly a pure gamble since theres no analysis involved.
Doing that will increase their chance of losing as they are just basing on their luck which is not the requirement to be profitable in sports betting.
Maybe for people who just want to have fun, they can do that but they should not be aggressive with the money they will risk, and for me, even if I am not so consistent in sports betting, to be able to analyze the game is just an another big add on for me to be entertain more.
