His videos are extremely entertaining, but his disregard for safety exaggerates the danger a little bit. My understanding is that most bridge rectifiers are put in a circuit after a step-down transformer, so they're operating on a much lower AC input voltage.
Also, don't wrap the safety ground pin on test equipment with kapton tape. Just don't.

Linear PSUs generally make ripply DC with linear power transformer -> rectifier and then use active linear analog circuits to get clean DC power. Has very low efficiency but exceedingly low noise. For most consumer things, you use a classic switch mode power supply design. You bridge rectify mains directly, and you switch that really fast to get the DC you need, and you filter it a lot.
