'Curry' (https://en.wikipedia.org/wiki/Curry) is a very general term, generally applied on cuisines from an outside perspective. In a particular area there may be a 'default' curry but this will differ widely in different places and contexts – "traditional Indian curry" is an understandable misconception, like saying there's a specific dish which is "standard Italian pasta".

Tikka Masala (https://en.wikipedia.org/wiki/Chicken_tikka_masala) is a more specific dish although there will be variation, a staple of British 'Indian' (which also includes Bangladeshi and Pakistani) cuisine.

So as noted in the comments, tikka masala is a type of curry.
