There can be slight differences between those backlinks that you can check in Moz, Ahrefs, SEMrush and others and those that actually are. The thing is that all those SEO software use their own crawler, like Google. And they have their own website database, like the index in Google.
To view a detailed list of your backlinks, go to Google Search Console -> Open "Links" in the bottom left corner -> Check External links.
But this can also not be the full list. Always use a couple of sources to get more detailed info.
