Evidence so far says they are not a gamble at all, and common (required?) eight year warranties on 80% life remaining are on all BEVs, plus record show that BEVs tend to to retain that 80% range at ten years. The gamble might be in whether the batteries have manufacturing defects, but warranty and recalls cover that, and as Samsung showed, can happen to even smaller, cheaper items.
