Even given the truth of those facts, it doesn't clearly put him ahead. Rizzo has never shat the bed like Bell did last year, for example.
Yes, Bell is probably a better player now, but to act like there's some massive gulf just isn't accurate. For one major thing, Bell is a DH who has to play a position. Rizzo isn't. Heck, Fangraphs even had Rizzo with a higher WAR number this year due to defense.
Shat the bed? Bell got COVID. And even with that horrendous start, he out hit Rizzo
