Many of those of this generation are not as avid in creating digital accounts (except for maybe facebook) on new platforms as younger generations...at least from how I have understood it from those who explained these things to me. So, you will find that those who are on things such as TikTok, reddit, Instagram and other social media in that line trend towards younger ages rather than older.
I might agree with this if you are talking about extreme numbers, but I think these things are pretty ubiquitous across all age groups. So might be true that 99% of young people are on social media, where "only" 95% of people in their 40s are but I don't think the difference is significant for what we are talking about.
