Trump got more votes in 2020 than he did in 2016, IIRC. While some people most likely did flip to Biden in 2020, there were also many, many people who voted 3rd-party in 2016 who didn't in 2020, and I think there was also higher voter turnout. The danger, as usual for Democrats, isn't people flipping to Trump, it's people not bothering to vote (or giving it to another party like the Greens) because they don't like the Dems' candidate. For the most part, Hillary didn't lose in 2016 because people voted for Trump instead of her; she lost because voters who normally would have voted (D) either stayed at home or voted for a protest party. Biden didn't have so much of a problem this way, for various reasons (voters liked him better to begin with, and they had just lived through the horrors of 4 years of a Trump presidency).
