Nice guys and bad boys have exactly the same low success rate when approaching women exactly
The difference is that bad boys hit on every woman they meet nearly. Despite the fact that they’re striking out generally, they still have the opportunity to find a date given that they swing frequently. They shrug off rejection and hit on someone else.
Nice guys, compared, work very slowly and only approach one woman they’re most considering. As long as they get rejected, they spend months or weeks licking their wounds before restarting the cycle.
