I had a bankrole of 0.001 from PD and won up to 0.12 but sadly the next day house edge got me, oh well thats my most victory in gambling.
you would not lucky as that for every day because in gambling if you are lucky with the small amount you can win big and the contrary if you aren't lucky very possible to lost with huge amount
For me it is a great luck of you to earn 0.12 with only 0.001 , I have never ever earned that much amount ever in my life maybe because of luck, But hope one day I will be able to do that.
I dont really think that 0.12 is really a big amount to win though. If you have let say 1 btc you will earn that 0.12 easily though. And if you start it from low amount you must really have more patient when you play it or you will lose everything and wasting your time
