TIL after undefeated boxer Billy Collins, Jr. was beaten so badly during his fight, his curious father insisted on shaking his opponent's hands. He discovered the fighter had removed all his padding, and eventually led to a 2.5 year prison sentence.

Okay I'm wrong about the deaths thing, but bare-knuckle boxing is still more dangerous than gloved boxing.

From your same Wikipedia page:

It should be noted that data for the number of fights and deaths from the bare-knuckle era is incomplete, and also that there were many differences in rules and medical care. Bare-knuckle boxing matches were usually fought until one fighter could not continue, with bouts sometimes lasting hours, and a few fighters dying after they were carried to their mark to restart the fight when they would otherwise have been unable to continue. (The London Prize Ring Rules later specifically stated that a fighter must "walk to his own side of the scratch unaided" (emphasis added) or lose the fight.) Bare-knuckle rules also allowed grappling and throws, and some of the deaths were caused by a fighter hitting his head on a stone or rail.

tl;dr - Your statistic is misleading because that 184x "higher" death count is due to vastly inferior medical care, insanely long fights (hours), and more dangerous ring conditions in the time of bare-knuckle boxing.

Furthermore, "In 100 years of bare-knuckle fighting in the United States, which terminated around 1897 with a John L Sullivan heavyweight championship fight, there wasn't a single ring fatality." and "Today, there are three or four every year in the US, and around 15 per cent of professional fighters suffer some form of permanent brain damage during their career.". That is with far superior facets in every part of boxing except for the gloves.
