Not necessarily. This doesn't scale upwards. It's not a restaurant. They don't have some kind of entitlement to a percentage of your win.
Think of grocery delivery services like Instacart. If I order a bunch of bulky but cheap stuff from Costco, I'm giving a high percentage tip, because it's a lot of effort for them, and the amount of money for my order isn't very high. However, if I order a few really expensive items which add up to $1000, I'm not giving them a $100 tip, even though it's only 10%. Why? Because the cost of the items shouldn't figure into this. They're simply getting items for me and bringing them, and I'm tipping them for their trouble.
Pretty much the same thing here.
