Learn English – I’ve won the lottery. This is the second time this happened

Common collocations are: to go skiing, to go swimming, etc. Thus, we say:

• I go swimming twice a week.
• We went skiing yesterday.
• They've gone skiing, but they should be back soon.
• I've been skiing three times this year.
• This is the first time I've been skiing.

In the last two examples been was used as the past participle of go. We use it to mean that somebody has gone somewhere and come back.

Here, therefore, have been skiing is not the present perfect continuous form of ski, but rather the present perfect simple of go skiing.

Special credits go to @Lambie and @userr2684291 for leading me in the right direction (see comments below the main post).

— [...] did you know our school team has won today's soccer match. (= recent news)
— [...] did you know our school team won today's soccer match. (= earlier in the morning, for example)

The choice hinges profoundly upon how recent is the action.
