So over the pandemic, I (in my mid 40's) went through ViBE's B2GM videos [1], and spending a couple of hours a week over six months or so managed to get up to Platinum 3 on the Starcraft 2 ladder; which, if I'm reading the stats right, means that (at that point) I would have been able to beat 50% of the people playing SC2 on the ladder. And there was still a lot of low-hanging fruit for me to deliberately practice when I moved on to some other projects in my precious free time. Now, you're not going to compete in SC2 with people who practice 10-20 hours a week unless you also practice 10-20 hours a week; but you can certainly get pretty good and have a lot of fun. (Maybe neurological limitations from being older would prevent you from being top-tier even if you did practice 10-20 hours a week; but I'm inclined to believe it's more that older people are less likely to practice 10-20 hours a week for whatever reason.)
