Snopes explains it as cherry picking:

The first thing to note about the rankings is that Lott has compared the mass shooting death rate in the United States with that of other countries where there was a mass shooting between 2009 and 2015. This might seem obvious, but it’s important to point out that very many countries did not see a single mass shooting as defined by Lott during this period.

The second striking thing about the list of mass shootings in Europe is that it is dominated by outliers. Where the United States saw at least twelve mass shooting deaths every year between 2009 and 2015, some of the other countries on Lott’s list experienced one or two rare but very high-casualty shootings. When you average out the death rates, this creates a highly misleading impression about the consistency and lethality of mass shootings outside the United States.

To further illustrate the point, even counting terrorism, Norway only has one significant event in the past 50 years, whereas it appears that not a day goes by in the USA without somebody shooting multiple people.

According to this 2012 article on gun homicides, the average per 100k people gun homicide rate was 4.9 globally, 3.0 for the US, and 0.4 for Europe (not counting Kosovo, Montenegro, and Russia due to missing data).
