I am a judoka myself but I do agree thaz judo is higher risk than wrestling generally. It s not even debatable IMO as it's obbiously ingrained in the Ippon mindset which encourages going for the one perfect/big throw that will win the fight in one second. If you miss your big throw you have options to reset.
In contrast, in wrestling it is much more about chaining attacks and continuous control in order to win on an accumulation of points. If you mess up a throw and give up your back you typically start losing points or at best you are in a shit position from which it will be tiring to get out or stall.
Then, on da streetz, turning throws, which tend to be more prevalent in judo, will typically be high impact and lead to a pin, which is pretty much fight ending. But fucking up your turning throw is not great with someone punching you and trying to gauge out your eyes. I think it's worse than messing up a wrestling leg attack.
Lastly, pretty much all judo throws rely on off balancing and timing to a greater extent than wrestling, which relies more on using strength at the right place. Therefore I think judo by design is more hit or miss.
