Yes, I KNOW this is the worst code you have probably seen, but please, this is my first big project and I do not know how to iterate this, I tried searching it up on youtube and look at other peoples code, never understood what they meant (as your not supposed to, unprofessional and pointless) so I took the long route.

The only issue I am facing is that the total winnings + total losses do not add up to the number of times repeated (yes, I know, my fault for doing it this way). Is there any way that I could improve this code by watching a YT video that shows automation like this, and what is the solution to solve the issue?
