No, France doesn't have "the stricter laws against guns" as she says around 3:20 because France has a hunting tradition and a strong hunting lobby. France has been hit specifically by terrorist attacks but overall the number of gun-related deaths per population in France is still about a gazillion times lower than in the US.

And saying that it's "highly unlikely that when we have stricter laws the people who want to murder people are going to obey those laws" is a fallacy and beyond the point. When you have stricter laws against guns the people who want to murder people should find it almost impossible or prohibitively expensive to get hold of an assault rifle and very, very hard to obtain a hand gun.

If the laws are well designed and well enforced. If the laws are not well enforced then you should vote for better politicians that change the officials in charge of enforcing the laws.

And the fact that laws were not enforced is never a justification not to try to craft better laws. "Ah, why bother ! Even the laws we have are not enforced so let's just sit by and wait for the next mass shooting ..."
