In his latest video on the coronavirus pandemic, Lionel talks about the measures being taken to control the spread of the virus in France. Like everyone else in the world, French people are trying to minimize the risk of catching the virus by staying inside and wearing masks when they have to go out.

Though risk is a major theme of the video, when Lionel uses the verb risquer, he means something a bit different: 

Lors du déconfinement,

During reopening,

nous risquons de sortir avec des masques

we're likely going out with masks

et... les distanciations sociales

and... social distancing

risquent de durer un bon moment.

is likely going to last for quite some time.

We don't "risk" going out with masks on, nor does social distancing "risk" lasting for a while longer. (Quite the contary: these are the very measures that are reducing risk). Risquer often just means "to be likely" (être probable) or "there's a good chance that." The stakes don't have to be that high:

Cette année, Noël risque d'être très présent dans les rues.

This year, Christmas is bound to be very present on the streets.

But risquer can also mean "to risk" or "run the risk of":

Si ça continue à cuire, ça risque de perdre sa belle couleur.

If they continue to cook, they run the risk of losing their beautiful color.

Il a risqué sa vie pour sauver le chien.

He risked his life to save the dog. 

Its noun form, risque, can mean "risk," "danger," or "chance." Note that, though it ends in an e, risque is masculine: 

Le risque avec les lamas, c'est qu'en grandissant,

The danger with llamas is that as they grow up,

ils peuvent devenir agressifs.

they may become aggressive.

There's also the adjective risqué, which you probably recognize. Though risqué can mean "racy" and "suggestive," as it does in English, it also just means "risky":

Pour elles c'est trop risqué de s'accrocher à la locomotive.

For them it's too risky to grab on to the engine.

Some say it's a good thing to take a lot of risks, but these days, that doesn't seem like the safest advice. Ne prenez pas de risque! (Don't take any risks!)
