bitcoin private key will can crack from a public key ....

it not easy (never happen)

not yet have any record for both bitcrack and kangaroo can crack on real key
kangaroo still can use on puzzle only (on low bit)

if crack mean calculate, it not correct at all

because method to use now is not calculate back to private key or calculate reverse it
kangaroo no any calculate to reverse key direct

kangaroo still RANDOM at all

now we still using method bruteforce on kangaroo
compare with bitcrack bitcrack use scan every private key on keyspace range

but kangaroo use method random by jump may be call smart random by using algorithm
if you read code and know how it works, you can see random command on kangaroo code work for random key

kangaroo not work with 256bit real key , until kangaroo scan to close up to nearly key around under 2**70 far form key and kangaroo jump to that fit center to key too
kangaroo still works only on low range low keyspace because still RANDOM it is slow like bitcrack

There is no such thing as absolute.
Test me
If you give me any public key, I can match the first and second digits of your private key.
