As I understand the lesson, faire du/de la is used for habitual activities and joue à is used for ongoing or current activities. Is this wrong?

If not, how come "Elle joue à la natation." is wrong for "She goes swimming"?

The lesson has "Tu fais de la natation" as an example where it means the person does this habitually/in a club or something. So wouldn't "Elle fait de la natation" mean "She swims", "She's in a swimming club" or something, i.e. that she swims habitually?

How come "en tout cas" is not an acceptable translation for "in any case"? To me, they mean the same thing but perhaps there is a difference in connotation?

Are the words 'LE rose' in the 1st sentence in the lesson, in the masculine gender because 'le rose' is used as a noun?  If the answer is yes, are all colours used as nouns masculine?
