Question: I want to express that I learning some courses will give me a good vision in a specific field. 

Can I say like "these courses take me on the way to the statistics"?

Answer: 
Maybe you want to say 

> 
> These courses should/will get me started on my way to learning/understanding statistics. 
> 
> 
> 

We can shorten this in several ways. 

> 
> These should get me on my way
> 
> 
> 

would be clear and idiomatic if your listener knows what you are talking about.

The sense of *way* here, means *heading toward* or *going in the direction of* some destination. We can assume that the destination you have in mind is the mastery of statistics to some degree. 

See <http://idioms.thefreedictionary.com/on+way>
I think it's not idiomatic to say:

These courses will take me on the way to the statistics.

I think you can rephrase your sentence as follows:

These courses will go a long way toward(s) learning statistics.

These courses will give a good insight into statistics.
