Take the blame? Or take the credit?

"The project had unavoidable difficulties. The supplier let us down.  I did try to make some suggestions, but the marketing was inadequate.  Sales teams didn't really pull their weight. And, boss, without wishing to be a snitch, one or two of the other team members didn't quite agree with your decisions."

Sure. None of the responsibility is yours. Any failure or problems can be laid at the feet of somebody else.  Or even blamed on an act of God.

But let me guess, when something goes really well, it's all on you.   Your readiness to blame others is a transparent weakness.  Confidence has no problem admitting when it's wrong.  Confidence has no problems discussing what it could have done better.  And confidence has no need to go grasping for credit.

There's a converse:  some people take the blame for everything but are too shy to take any credit.  Praise is deflected:  "Oh, thanks, but really I didn't do much - it was the other guys who made it happen".  Criticism leads to self-flagellation and introspection.

Balance is missing in both of these.  If you're going to take the credit then you have to be prepared to shoulder the blame.  And if you're busy blaming yourself for everything then stand up and be counted when things go well.

Find balance. The more you can accept your part in things going wrong, the more right you have to stake your claim when things go well.
