Bangladesh have actually won a similar amount of their first 100 tests than a few other sides, including those that had decades to establish themselves rather than what Bangladesh have now which is only their second generation of test players. But they've lost far, far more and this is despite going through a long period of actually trying to draw Tests at home. Does their record being the worst indicate where they're staying? Probably not. But it does feel like, if Bangladesh are now an established side, they might have skipped a step.
