The Claim
Age (younger vs. older adults) does not significantly moderate the effect of resistance training velocity on strength adaptations, with no significant difference between subgroups (QM = 0.09, p = 0.77), though younger adults showed a small significant benefit for fast training (Hedges' g = 0.23, p = 0.049) while older adults showed no preference (Hedges' g = 0.16, p = 0.46), based on 20 younger and 5 older studies.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Whether you're young or old doesn't really change how fast or slow weight training affects your strength gains. Young people might get a tiny extra boost from fast lifting, but for older folks, it doesn't make much difference either way.

What the research says
1 studyStudy: Intentionally Slow Concentric Velocity Resistance Exercise and Strength Adaptations: A Meta-Analysis
The study looked at how fast or slow weight training affects strength in different ages and found that age doesn't really change which speed is better, just like the claim says.
