They are not conflicting but I can see how you might think that. Pollen is plant sperm. In order for pollination to occur many plants have special needs. The pollen has to be “picked up” and transferred to the female stigma. One example of how honeybees take nectar but don’t pollinate flowers are flowers that require “buzz pollinating”.

Hope that clears things up. Happy to answer anymore questions (I am just someone who is passionate about nature I’m not a professional or anything).

You basically got it. European honey bees consume the already dwindling nectar and pollen resources for North American native pollinators. Furthermore, European honey bees are also worse at actually pollinating North American flowers because they did not co-evolve with the species we have here.
