I would probably say "gain", but I'm not aware of there being any consensus on this terminology.

you're right. i knew it wasn't well defined but i was too lazy to distinguish, lol

how would you say it? to gain 100k? or just "to make 100k profit"?

I think it largely gets confusing because "win" is used in two different ways. 

In your example, winning 100k on a 50k bet means you walk away with 150k, 

Sometimes, though, winning 100k just means that's what you walk away with, so that would be 1:1 odds on a 50k wager.
