Yup - they will still be young 4 years from now - only Lloris, Matudi, & Giroud are over 30. Them and England are two of the youngest teams in the tournament.

These guys are all still young enough to play in 2022 and could even be better then:
Pavard - 22
Varane - 25
Umtiti - 24
Hernandez - 22
Mendy - 23
Pogba - 25
Lemar - 22
Tolisso - 23
Kante - 27
Fekir - 24
Griezmann - 27
Mbappe - 19
Dembele - 21
Thauvin - 25
Plus you have these guys not even on the squad:
Digne - 24
Zouma - 23
Coman - 22
Rabiot - 23
Martial - 22
Bakayoko - 23
Laporte - 24
This team should be a force at Euro 2020 and World Cup 2022 but of course you never know. Germany had a really young team in 2014 and looked poised to repeat...we all know what happened there though.
