At worse I think we will find we're flipping, which for 50bb isn't bad. It's also very naive to use his stats of 60/19 in a blind v blind spot. Raising 19% of hands is still quite high in general and it's bvb spot so obviously we can increase that by a lot more than 19%. It's unlikely he's open shoving like nutted hands here, and we block the AA/KK hands and I expect to see hands we dominate a lot and of course the small medium pairs we're flipping against. It's unlikely he's doing this with say QQ and even then, it's not a horrible spot to be in.
Not sure how you come to a 60% equity spot, but even if that was the case taking a 60% equity spot is good in a tournament especially is good. It's for sure a +EV call and +cEV it's not as if ICM is a factor either.
