Exactly, most of the experience will not bother about the risk because managing funds are always good in order to reduce the loss. So without calculation, it is impossible for a trader to make a profit, we need to restrict ourselves otherwise, we are going to lose a huge amount of money.
It is important to gain experience but it does not mean the risks will reduce. Managing funds is one thing but going broke and not having enough bankroll to spend with checks is a tough thing. For any trader readily available cash is important too. They want to take every opportunity at making money but then again they need to keep bankroll in check. So it boils down to how much risk they are willing to take and how many trades then are executing.
You may play the long game and work with smaller portfolio with a big capital. That is good for most traders.
