Jax is banned in about 8.2% of games at this tier, one figure for the whole champion since bans happen before roles are picked. What ban rate measures.
Jax's Top win rate is 0.7 percentage points below an even 50% — Should I Dodge's win-probability model varies by about 4.8 percentage points of standard deviation from lobby to lobby across all ranks, purely from which champions get drawn, so this gap is smaller than that noise, not solid evidence the champion is unusually strong or weak right now.
Jax is tracked in 2 roles at this tier scope; the per-tier, threat, and counters reporting below all use its highest-pick-rate role, Top — its numbers in Jungle (1.9% pick rate) stay visible in the table above but aren't carried into the rest of this page.
