Imagine just wage a small amount of but course all of his hard work and time effort imagine already paid with that event even though I play a lot still got a smaller chance to win with that event well of course still a big congratulation to you buddy that's why the gambling is full of luck you can't tell when is your lucky day.
there are pure luck gambling games and some others are also based in skill
take poker as an example
you can get lucky, but it's way more about skill than luck only
different than roulette or slots...
