Understanding these sayings: Have a shot at, Have a crack at, have a go at...

[english-learner]

Hello,

I want to know that are these phrases here mean the same:

Have a shot at, Have a whack at, Have crack at, Have a go at, Take a shot at, Take a crack at and Get a shot at.

If not, is there any difference between all of them?

Thanks,

Not in meaning- certain contexts will see certain collocations:

Come and have a go if you think you're hard enough.

Here, I would only use 'go'.

[english-learner]

Can you tell you what are those phrases mean? Also, I don't quite get what does the sentence that you show me mean.

Thank you,

Try, make an attempt, especially if you don't think you have much chance, but nothing to lose.

Come and have a go if you think you're hard enough.- Originally this was a chant by British football hooligans, meaning 'come and fight if you think you are strong enough', but it has passed into general use as a way of challenging someone.

Do all of these phrases also mean have a real chance or possibility of doing something or have a turn at doing something?

Get a shot = have an opportunity, because you are given it. The others just mean try to me.

How about this one righ here:

LAMBEAU
Sean, you know what the odds are against winning the lottery?

SEAN
What? Four to One?

LAMBEAU
About 7,000,000 to one.

SEAN
I still have a shot.

Also other one here:

ANGELA
No, I liked it. And I still like it. If people I don't even know look at me and want to fuck me, it means I really have a shot at being a model. Which is great, because there's nothing worse in life than being ordinary.


In this two cases, do they all mean having a real chance or possibility of doing it?

Thank you,
